Subject: [PATCH] arm/arm64: KVM: Ensure memslots are within KVM_PHYS_SIZE

When creating or moving a memslot, make sure the IPA space is within the
addressable range of the guest.  Otherwise, user space can create too
large a memslot and KVM would try to access potentially unallocated page
table entries when inserting entries in the Stage-2 page tables.
