do not destroy 'snapdir' when it becomes inactive
That was just wrong. In fact, we can safely keep this static entry when
it's inactive.
Now the destructive action is moved to the reclaim method and the
function is renamed from zfsctl_snapdir_inactive(0 to
zfsctl_snapdir_reclaim().
Also, we can use gfs_vop_reclaim() instead of gfs_dir_inactive() +
kmem_free().
Lastly, we can just assert that the node does not any children when it
is reclaimed, even on the force unmount. That's because zfs_umount()
does an extra vflush() pass which should destroy all snapshot-mountpoint
vnodes that are the snapdir's children.

In fact, that was dangerous. For example, zfsctl_snapshot_reclaim()

directory vnode lock after the child's vnode lock.
Also, the previous behavior was inconsistent as gfs_dir_lookup()
returned a locked vnode for . and .. lookups, but not for any other.
Now gfs_lookup_dot() just references a resulting vnode and the locking
is done in its consumers, where necessary.

avoid deadlock between zfsctl_snapdir_lookup and zfsctl_snapshot_reclaim
The former acquired a snap vnode lock while holding sd_lock while the
latter does the opposite.
The solution is drop sd_lock before acquiring the vnode lock. That
should be okay as we are still holding a lock on the 'snapshot'
directory in the exclusive mode. That lock ensures that there are no
concurrent lookups in the directory and thus no concurrent mount attempts.
But now we have to account for the possibility that the snap vnode
might get reclaim after we drop sd_lock and before we can get
the node lock. So, check for that case and retry.
