Print out the test and vector as intended when a guest assert fails an
assertion regarding MONITOR/MWAIT faulting. Unfortunately, the guest
printf support doesn't detect such issues at compile-time, so the bug
manifests as a confusing error message, e.g. in the most confusing case,
the test complains that it got vector "0" instead of expected vector "0".
Fixes: 0f52e4aaa6 ("KVM: selftests: Convert the MONITOR/MWAIT test to use printf guest asserts")
