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.
