rt2x00: fix rfkill regression on rt2500pci

commit 616a8394b5df8c88f4dd416f4527439a4e365034 upstream.

As reported by Niels, starting rfkill polling during device probe
(commit e2bc7c5, generally sane change) broke rfkill on rt2500pci
device. I considered that bug as some initalization issue, which
should be fixed on rt2500pci specific code. But after several
attempts (see bug report for details) we fail to find working solution.
Hence I decided to revert to old behaviour on rt2500pci to fix
regression.

Additionally patch also unregister rfkill on device remove instead
of ifconfig down, what was another issue introduced by bad commit.
