Josh Triplett 22d91f65d5 [XFS] Add lock annotations to xfs_trans_update_ail and
xfs_trans_delete_ail

xfs_trans_update_ail and xfs_trans_delete_ail get called with the AIL lock
held, and release it. Add lock annotations to these two functions so that
sparse can check callers for lock pairing, and so that sparse will not
complain about these functions since they intentionally use locks in this
manner.
