x86/kvm: Introduce kvm_(un)map_gfn()
commit 1eff70a9abd46f175defafd29bc17ad456f398a7 upstream.
kvm_vcpu_(un)map operates on gfns from any current address space.
In certain cases we want to make sure we are not mapping SMRAM
and for that we can use kvm_(un)map_gfn() that we are introducing
in this patch.
This is part of CVE-2019-3016.
