[PATCH 03/20] Rename scsi_softirq_done() into scsi_complete()

[Bart Van Assche <bvanassche@acm.org>]

Commit 320ae51feed5 ("blk-mq: new multi-queue block IO queueing mechanism";
v3.13) introduced a code path that calls the blk-mq completion function from
interrupt context. scsi-mq was introduced by commit d285203cf647 ("scsi:
add support for a blk-mq based I/O path."; v3.17). Since the introduction of
scsi-mq scsi_softirq_done() can be called from interrupt context. Because
that made the name of that function misleading, rename it into
scsi_complete().
