blk_end_request: changing block layer core (take 4)
This patch converts core parts of block layer to use blk_end_request
interfaces. Related 'uptodate' arguments are converted to 'error'.
'dequeue' argument was originally introduced for end_dequeued_request(),
where no attempt should be made to dequeue the request as it's already
dequeued.
However, it's not necessary as it can be checked with
list_empty(&rq->queuelist).
(Dequeued request has empty list and queued request doesn't.)
And it has been done in blk_end_request interfaces.
As a result of this patch, end_queued_request() and
end_dequeued_request() become identical. A future patch will merge
and rename them and change users of those functions.
