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.

analysis.

Under a sequential create+allocate workload, blktrace reported backward
writes being issued by xfsbufd, and frequent inappropriate queue unplugs.
We now insert at the tail when moving from the delwri lists to the temp
lists, which maintains correct ordering, and we avoid unplugging queues
deep in the submit paths when we'd shortly do it at a higher level anyway.
blktrace now reports much healthier write patterns from xfsbufd for this
workload (and likely many others).
