Subject: [PATCH 1/3] KVM: selftests: Test MONITOR and MWAIT, not just MONITOR
 for quirk

Fix a copy+paste error in monitor_mwait_test by switching one of the two
"monitor" instructions to  an "mwait".  The intent of the test is very
much to verify the quirk handles both MONITOR and MWAIT.

Fixes: 2325d4dd7321 ("KVM: selftests: Add MONITOR/MWAIT quirk test")
