scsi: core: Rename scsi_softirq_done() into scsi_complete()

Commit 320ae51f ("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 d285203c
("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().
