I think I have a slight preference for leaving kvm_gpc_refresh()
working on a GPA unconditionally, thus calling __kvm_gpc_refresh() with
the final argument set to true.
Introduce another one-line wrapper kvm_gpc_refresh_hva() for the false
case. And perhaps BUG_ON() calling the 'wrong' refresh function?
