net: stmmac: disable PTP clock after unregistering PTP 



Follow the principle of unpublish from userspace and then teardown
resources.

Disable the PTP clock only after unregistering with the PTP subsystem,
which ensures that we only stop the clock that ticks the timesource
after we have removed the PTP device.
