[PATCH 1/4] KVM: x86: mark synthetic SMM vmexit as SVM_EXIT_SW

[Maxim Levitsky]

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.
