powerpc/kvm: Fix "PR" KVM implementation of H_CEDE

H_CEDE should enable the vcpu's MSR:EE bit. It does on "HV" KVM (it's burried in the assembly code though) and as far as I can tell, qemu does it as well. Signed-off-by: Benjamin Herrenschmidt <[email protected]> Signed-off-by: Alexander Graf <[email protected]>
