Remove some wrappers that we have in XFS around the read-write semaphore

The goal of this cleanup is to remove mrlock_t structure and its mr*()
wrapper functions and replace it with native rw_semaphore type and its
native calls.

Hmmm, there's something funny about this patchset that causes my fstests
vm to explode with isilocked assertions everywhere... I'll look more
tomorrow (it's still the weekend here) but figured I should tell you
sooner than later.
