Any driver that uses SCSI bus reset for last-resort error recovery
(and I think it's pretty typical) needs to be able to renegotiate the
connection. Maybe even after a SCSI device reset; I don't recall. So
initiating that negotiation as part of (or after) resume doesn't seem
all that burdensome.
You need that anyway for "deep sleep" that powers down devices completely.
