xfs: combine xfs_trans_ail_[remove|delete]()

Now that the functions and callers of
xfs_trans_ail_[remove|delete]() have been fixed up appropriately,
the only difference between the two is the shutdown behavior. There
are only a few callers of the _remove() variant, so make the
shutdown conditional on the parameter and combine the two functions.

/**
* Remove a log items from the AIL
*
* @xfs_trans_ail_delete_bulk takes an array of log items that all need to
* removed from the AIL. The caller is already holding the AIL lock, and done
* all the checks necessary to ensure the items passed in via @log_items are
* ready for deletion. This includes checking that the items are in the AIL.
*
* For each log item to be removed, unlink it from the AIL, clear the IN_AIL
* flag from the item and reset the item's lsn to 0. If we remove the first
* item in the AIL, update the log tail to match the new minimum LSN in the
* AIL.
*
* This function will not drop the AIL lock until all items are removed from
* the AIL to minimise the amount of lock traffic on the AIL. This does not
* greatly increase the AIL hold time, but does significantly reduce the amount
* of traffic on the lock, especially during IO completion.
*
* This function must be called with the AIL lock held. The lock is dropped
* before returning.
