Pull xfs fixes from Darrick Wong:
 "Fixes for a resource leak and a build robot complaint about totally
  dead code:

   - Fix buffer resource leak that could lead to livelock on corrupt fs.

   - Remove unused function xfs_inew_wait to shut up the build robots"

* tag 'xfs-5.16-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
