Subject: [PATCH v4 06/14] blk-mq: remove unncessary from_schedule parameter in blk_mq_plug_issue_direct

Function blk_mq_plug_issue_direct tries to issue batch requests in plug
list to driver directly. We will only issue plug request to driver if we
are not from scheduler, so from_scheduler parameter of
blk_mq_plug_issue_direct is always false.
Remove unncessary from_scheduler of blk_mq_plug_issue_direct.
