selftests, x86, protection_keys: fix wrong offset in siginfo
The siginfo contains a bunch of information about the fault. For protection keys, it tells us which protection key's permissions were violated. The wrong offset in here leads to reading garbage and thus failures in the tests. We should probably eventually move this over to using the kernel's headers defining the siginfo instead of a hard-coded offset. But, for now, just do the simplest fix.
