xfs: shut up -Wuninitialized in xfsaild_push
-Wuninitialized complains about @target in xfsaild_push being uninitialized in the case where the waitqueue is active but there is no last item in the AIL to wait for. I /think/ it should never be the case that the subsequent xfs_trans_ail_cursor_first returns a log item and hence we'll never end up at XFS_LSN_CMP, but let's make this explicit.
