[iscsi] Report SCSI response only when applicable
iSCSI generally includes a full SCSI response only when an error
occurs. iscsi_scsi_done() currently passes the NULL response through
to scsi_response(), which ends up causing scsicmd_response() to
dereference a NULL pointer.
Fix by calling scsi_response() only if we have a non-NULL response.
