Two cleanups with no functional changes. I'm not 100% on whether or not open coding the private memslot check in patch 2 is a good idea. Avoiding the extra memslot lookup is nice, but that could be done by providing e.g. kvm_is_memslot_visible(). On one hand, I like deferring the nonexistent and invalid checks to common code, but on the other hand it creates the possibility of missing some future case where kvm_is_gfn_visible() adds a check that's not also incoporated into __gfn_to_hva_many(), though that seems like a rather unlikely scenario.
