KVM: selftests: Extend the invalid nVMX guest state test to cover RSM

Browse source

Extend the invalid nVMX guest state to cover RSM, i.e. to validate that KVM
synthesizes SHUTDOWN for L1 if SMRAM is clobbered with invalid guest state
during an L2 => SMI => RSM => L2 sequence.

Note, unlike the existing testcase, clobbering SMRAM should result in L1,
not L2, getting SHUTDOWN / TRIPLE_FAULT, as RSM is architecturally defined
to trigger shutdown if the CPU detects invalid state.
