KVM: arm64: nv: Turn encoding ranges into discrete XArray stores

Browse source

In order to be able to store different values for member of an
encoding range, replace xa_store_range() calls with discrete
xa_store() calls and an encoding iterator.

We end-up using a bit more memory, but we gain some flexibility
that we will make use of shortly.

Take this opportunity to tidy up the error handling path.
