netpoll: prevent netpoll setup on slave devices

In commit 326e9872c04625b06aaac6ac002c520d48098b62
(netpoll: disable netpoll when enslave a device), we automatically
disable netpoll when the underlying device is being enslaved,
we also need to prevent people from setuping netpoll on
devices that are already enslaved.
