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 <benh@kernel.crashing.org> Signed-off-by: Alexander Graf <agraf@suse.de>
