[PATCH] scsi: sun3: Mark driver struct with __refdata to prevent section mismatch

[Geert Uytterhoeven <geert@linux-m68k.org>]

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 warnings

    WARNING: modpost: drivers/scsi/sun3_scsi: section mismatch in reference: sun3_scsi_driver+0x4 (section: .data) -> sun3_scsi_remove (section: .exit.text)
    WARNING: modpost: drivers/scsi/sun3_scsi_vme: section mismatch in reference: sun3_scsi_driver+0x4 (section: .data) -> sun3_scsi_remove (section: .exit.text)

that trigger on a Sun 3 allmodconfig build.
