Radim Krčmář 9cf0eaf88d KVM: x86: fix APIC page invalidation
commit b1394e745b upstream.

Implementation of the unpinned APIC page didn't update the VMCS address
cache when invalidation was done through range mmu notifiers.
This became a problem when the page notifier was removed.

Re-introduce the arch-specific helper and call it from ...range_start.
