scsi: mac_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/mac_scsi: section mismatch in reference: mac_scsi_driver+0x8 (section: .data) -> mac_scsi_remove (section: .exit.text)
that triggers on an allmodconfig W=1 build.
