Unmap KVM-created VMAs for KVM-internal memslots when the associated
memslot is freed instead of unmapping via x86's internal API.  This will
allow deleting/freeing all memslots before kvm_arch_destroy_vm() without
leaking VMAs, and in general is a net positive as it makes it far less
likely that KVM will leak VMAs, e.g. in the unlikely scenario some other
flow deletes KVM-internal memslots without going through
__x86_set_memory_region().

LGTM; this code is so much better. Feel free to add:
