hpsa: fix non-x86 builds
commit 28e13446 "[SCSI] hpsa: enable unit attention reporting" turns on unit attention notifications, but got the change wrong for all architectures other than x86, which now store an uninitialized value into the device register. Gcc helpfully warns about this: ../drivers/scsi/hpsa.c: In function 'hpsa_set_driver_support_bits': ../drivers/scsi/hpsa.c:6373:17: warning: 'driver_support' is used uninitialized in this function [-Wuninitialized] driver_support |= ENABLE_UNIT_ATTN; ^ This moves the #ifdef so only the prefetch-enable is conditional on x86, not also reading the initial register contents.
