selftests, x86, protection_keys: fix wrong offset in siginfo
commit 2195bff041486eb7fcceaf058acaedcd057efbdc upstream.
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.
