SCSI: Reset flags on the correct request in submit_autosense.

The passed request is the one triggering the auto-sense, not
the auto-sense itself.

Resetting the "buffered" flag on the wrong request meant that
if a buffer had been used for the triggering request, it would
be leaked, and subsequently we would get KDLs when trying to
unlock memory that wasn't actually locked at all.

Fixes #19218 and related tickets.
