Pull xfs bugfixes from Ben Myers:
 "Here we have a bugfix for an off-by-one in the remote attribute
  verifier that results in a forced shutdown which you can hit with v5
  superblock by creating a 64k xattr, and a fix for a missing
  destroy_work_on_stack() in the allocation worker.

  It's a bit late, but they are both fairly straightforward"
