On a non-pKVM nVHE host, the hyp callers of this in switch.c and
timer-sr.c now translate vcpu->kvm and load vm_flavor on every guest
entry and exit, where the is_protected_kvm_enabled() check used to
short-circuit. Could they use vcpu_is_protected_pkvm(), and drop the
kern_hyp_va() here?

With that:
