[PATCH 16/18] scsi: target: drop tas arg from __transport_wait_for_tasks

[Mike Christie <michael.christie@xxxxxxxxxx>]

The tas arg is no longer used by callers of __transport_wait_for_tasks
so drop it. Also, fix up comment about us skipping the put, when TAS is
not set because that was not correct as we always did the put.
