blk-mq: remove unncessary error count and commit in blk_mq_plug_issue_direct

We need only to explicitly commit in two error cases:
 -did not queue everything initially scheduled to queue
 -the last attempt to queue a request failed
(see comment of blk_mq_commit_rqs for more details).
Both cases can be checked with ret of last request which breaks list walk.
Remove unnecessary error count and unnecessary commit triggered by error
which is not covered by cases described above.
