scsi: cleanup scsi_clear_unit_attention()
The previous commit moved the unit attention clearing when we create
the request. So now we can clean scsi_clear_unit_attention() to handle
only the case of the REPORT LUNS command: this is the only case in
which a UNIT ATTENTION is cleared without having been reported.
