scsi-disk: allow the MODE_PAGE_R_W_ERROR AWRE bit to be changeable for CDROM drives
A/UX sends a MODE_PAGE_R_W_ERROR command with the AWRE bit set to 0 when enumerating CDROM drives. Since the bit is currently hardcoded to 1 then indicate that the AWRE bit can be changed (even though we don't care about the value) so that the MODE_PAGE_R_W_ERROR page can be set successfully.
