KVM: x86/mmu: Detect if unprotect will do anything based on invalid_list
Explicitly query the list of to-be-zapped shadow pages when checking to see if unprotecting a gfn for retry has succeeded, i.e. if KVM should retry the faulting instruction. Add a comment to explain why the list needs to be checked before zapping, which is the primary motivation for this change. No functional change intended.
