clocksource: Unregister subsystem on device registration failure
init_clocksource_sysfs() registers the clocksource subsystem before
registering the clocksource device. If device_register() fails, the
function returns the error while leaving the subsystem registered.
Unregister the clocksource subsystem on that failure path so the
successful subsystem registration is unwound before returning.
Fixes: d369a5d8fc70 ("clocksource: convert sysdev_class to a regular subsystem")
