Pull xfs fixes from Darrick Wong:

 - fix firstfsb variables that we left uninitialized, which could lead
   to locking problems.

 - check for NULL metadata buffer pointers before using them.

 - don't allow btree cursor manipulation if the btree block is corrupt.
   Better to just shut down.

 - fix infinite loop problems in quotacheck.

 - fix buffer overrun when validating directory blocks.

 - fix deadlock problem in bunmapi.
