scsi: core: Rename scsi_softirq_done() into scsi_complete()
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. That made the name of the function misleading, rename it to scsi_complete().
