blk_end_request: cleanup of request completion (take 4)
This patch merges complete_request() into end_that_request_last()
for cleanup.
complete_request() was introduced by earlier part of this patch-set,
not to break the existing users of end_that_request_last().
Since all users are converted to blk_end_request interfaces and
end_that_request_last() is no longer exported, the code can be
merged to end_that_request_last().
