HAMMER VFS - Unlock around uiomove

* Unlock the uncached read path's lock and the write path's lock
  around the uiomove().  The cached read path is already unlocked
  around the uiomove().

* Results in a marginal improvement in concurrency.  Full buffers (64K)
  are large enough to warrent the unlock/relock.
