xfs: pass along transaction context when reading directory block buffers

Source kernel commit: acb9553cab552cf17154814f079f54401eefa474

Teach the directory reading functions to pass along a transaction context
if one was supplied.  The directory scrub code will use transactions to
lock buffers and avoid deadlocking with itself in the case of loops.
