Userspace isn't allowed to access certain address ranges, make sure we actually test that to at least some degree. This would have caught the recent bug where the SLB fault handler was incorrectly called on an out-of-range access when using the Radix MMU. It also would have caught the bug we had in get_region_id() where we were inserting SLB entries for bad addresses.
