Srikar Dronamraju a21d1becaa powerpc: Reintroduce is_kvm_guest() as a fast-path check 
Introduce a static branch that would be set during boot if the OS
happens to be a KVM guest. Subsequent checks to see if we are on KVM
will rely on this static branch. This static branch would be used in
vcpu_is_preempted() in a subsequent patch.
