Mark Johnston 46b2623586 Allow disabling of unmapped I/O on FreeBSD ...

We have a tunable which permits one to disable the use of unmapped I/O
for the buffer cache.  Respect it in ZFS as well.  This is useful for
KMSAN, which cannot easily maintain shadow state for unmapped pages.

No functional change intended, as unmapped I/O is permitted by default
and there's no real reason to disable it in practice except for
debugging.
