x86/PVH: properly disable vLAPIC

Rather than guarding higher level operations (like vPMU initialization
as suggested by Boris in
http://lists.xenproject.org/archives/html/xen-devel/2014-11/msg02278.html)
mark the vLAPIC hardware disabled for PVH guests and prevent it from
getting moved out of this state.
