stand: Unbreak FAT32 in loader
This corrects an issue introduced in b4cb3fe0e39a3, where a freshly
allocated `DOS_FS` structure would not be initialized properly before
use in `dos_open`.
In case of FAT32 file systems, this would leave `fs->dirents`
uninitialized and - depending on its content and due to checks in
`parsebs` - prevent mounting the file system successfully.
This particularily impacted the EFI loader, as it was sometimes not
able to read files from a FAT32-formatted EFI partition, including
LoaderEnv (`/efi/freebsd/loader.env`).

powerpc64: make radix with superpages default
As Radix MMU with superpages enabled is now stable, make it the
default choice on supported hardware (POWER9 and above), since its
performance is greater than that of HPT MMU.

powerpc/pseries: Allow radix pmap in pseries for ISA 3.0
ISA 3.0 allows for nested radix translations with minimal to no
involvement of the hypervisor. This should make pseries signficantly
faster on POWER9 pseries instances, as fewer hypercalls are needed to
manage pmap now.

powerpc64le: fix boot when using QEMU PowerNV
When using QEMU PowerNV with latest op-build release (v2.7), its

sched_4bsd: Fix a racy thread state modification
When a thread switching off-CPU is migrating to a remote CPU,
sched_switch() may trigger a rescheduling of the thread currently
running on that CPU. When doing so, it must ensure that that thread is
locked before modifying thread state. If the thread's lock is not the
scheduler lock, then the thread is in the process of switching off-CPU
and no extra effort is needed, and the initiator does not hold the
thread's lock and thus should not modify any thread state.
