Paolo Bonzini c36b71503a KVM: x86/mmu: Avoid an extra memslot lookup in try_async_pf() for L2
Create a new function kvm_is_visible_memslot() and use it from
kvm_is_visible_gfn(); use the new function in try_async_pf() too,
to avoid an extra memslot lookup.

Opportunistically squish a multi-line comment into a single-line comment.

Note, the end result, KVM_PFN_NOSLOT, is unchanged.
