KVM: x86: mark synthetic SMM vmexit as SVM_EXIT_SW
Use a dummy unused vmexit reason to mark the 'VM exit' that is happening
when kvm exits to handle SMM, which is not a real VM exit.
This makes it a bit easier to read the KVM trace, and avoids
other potential problems due to a stale vmexit reason in the vmcb.
If SVM_EXIT_SW somehow reaches svm_invoke_exit_handler(), instead,
svm_check_exit_valid() will return false and a WARN will be logged.
