scsi: atari_scsi: Mark driver struct with __refdata to prevent section mismatch

As described in the added code comment, a reference to .exit.text is ok for
drivers registered via module_platform_driver_probe(). Make this explicit
to prevent the following section mismatch warning

	WARNING: modpost: drivers/scsi/atari_scsi: section mismatch in reference: atari_scsi_driver+0x8 (section: .data) -> atari_scsi_remove (section: .exit.text)

that triggers on an allmodconfig W=1 build.
