ZTS: Fix enospc_002_pos.ksh again
This is a follow up commit for e03a41a60 which aimed to resolve
this same test failure. The core "problem" here is that it takes
very little space to perform a clone/snapshot/bookmark, which
means if we want these commands to reliably fail the pool must
truely have exhausted all free space.
This commit increases the number of fill iterations to try and
consume every block which we can. This still can't guarantee
the clone/snapshot/bookmark will fail, but it significantly
improves the odds. The exception was kept since it's still
not a sure thing.

zfs: Fix a deadlock between page busy and the teardown lock
When rolling back a dataset, ZFS has to purge file data resident in the
system page cache. To do this, it loops over all vnodes for the
mountpoint and calls vn_pages_remove() to purge pages associated with
the vnode's VM object. Each page is thus exclusively busied while the
dataset's teardown write lock is held.
When handling a page fault on a mapped ZFS file, FreeBSD's page fault
handler busies newly allocated pages and then uses VOP_GETPAGES to fill
them. The ZFS getpages VOP acquires the teardown read lock with vnode
pages already busied. This represents a lock order reversal which can
lead to deadlock.
To break the deadlock, observe that zfs_rezget() need only purge those
pages marked valid, and that pages busied by the page fault handler are,
by definition, invalid. Furthermore, ZFS pages always transition from
invalid to valid with the teardown lock held, and ZFS never creates
partially valid pages. Thus, zfs_rezget() can use the new
vn_pages_remove_valid() to skip over pages busied by the fault handler.

Linux 5.13 compat: retry zvol_open() when contended
Due to a possible lock inversion the zvol open call path on Linux
needs to be able to retry in the case where the spa_namespace_lock

For Linux 5.12 an older kernel this was accomplished by returning
-ERESTARTSYS from zvol_open() to request that blkdev_get() drop
the bdev->bd_mutex lock, reaquire it, then call the open callback
again. However, as of the 5.13 kernel this behavior was removed.
Therefore, for 5.12 and older kernels we preserved the existing
retry logic, but for 5.13 and newer kernels we retry internally in
zvol_open(). This should always succeed except in the case where
a pool's vdev are layed on zvols, in which case it may fail. To
handle this case vdev_disk_open() has been updated to retry when
opening a device when -ERESTARTSYS is returned.

- Allocate ve_search on the stack, so we avoid allocating memory for
every I/O even if the VDEV cache is disabled.
- Reduce lock scope.
- Avoid locking in vdev_cache_read() when the VDEV cache is disabled.
- Sort file names properly.
- Correct comment.

The wins for a relatively normal workload are rather slim:
real 0.02119s/0.00985s=2.15029x
user 0.02130s/0.00346s=6.15560x
sys 0.03858s/0.00643s=6.00062x
But this is a big win on machines with a lot of datasets and expensive
forks.
For example, the gain on a VM on my work laptop with 900+ legacy-mount
Docker datasets, the original gains from the C rewrite were
only five-fold:
real 0.516s/0.102s=5.05882x
user 0.237s/0.143s=1.65734x
sys 0.287s/0.100s=2.87x
And this serial variant gains this back there as well:
real 0.102s/0.008s=12.75x
user 0.143s/0.007s=20.42857
sys 0.100s/0.001s=100x
