xfs: defered work could create precommits
To fix a AGI-AGF-inode cluster buffer deadlock, we need to move
inode cluster buffer operations to the ->iop_precommit() method.
However, this means that deferred operations can require precommits
to be run on the final transaction that the deferred ops pass back
to xfs_trans_commit() context. This will be exposed by attribute
handling, in that the last changes to the inode in the attr set
state machine "disappear" because the precommit operation is not run.
