kvm: Return -ENODEV from update_persistent_clock
kvm does not support setting the RTC, so the correct result is -ENODEV. Returning -1 will cause sync_cmos_clock to keep trying to set the RTC every second. Signed-off-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
