KVM: arm64: Make fault_ipa immutable

Browse source

Updating fault_ipa is conceptually annoying, as it changes something
that is a property of the fault itself.

Stop doing so and instead use fault->gfn as the sole piece of state
that can be used to represent the faulting IPA.

At the same time, introduce get_canonical_gfn() for the couple of case
we're we are concerned with the memslot-related IPA and not the faulting
one.
