scsi: aha152x: Fix aha152x_setup() __setup handler return value

__setup() handlers should return 1 if the command line option is handled
and 0 if not (or maybe never return 0; doing so just pollutes init's
environment with strings that are not init arguments/parameters).

Return 1 from aha152x_setup() to indicate that the boot option has been
handled.
