In a scenario where there isn't any firmware available, we will have a
double kfree of rt2x00dev->spec.channels_info when ieee80211_register_hw
returns an error status inside rt2x00lib_probe_hw.

The problem is that if ieee80211_register_hw fails, we call
rt2x00lib_remove_hw twice:
* first inside rt2x00lib_probe_hw upon failure of ieee80211_register_hw
* error status is returned to rt2x00lib_probe_dev, which then sees it and
  calls in this case rt2x00lib_remove_dev that will again run
  rt2x00lib_remove_hw

Prevent this avoiding calling rt2x00lib_remove_hw inside
rt2x00lib_probe_hw

Problem was detected with CONFIG_DEBUG_PAGEALLOC=y, CONFIG_SLUB_DEBUG=y,
CONFIG_SLUB_DEBUG_ON=y, that dumps this with no firmware available:

rt61pci 0000:00:07.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19

phy0: Selected rate control algorithm 'pid'

This will break my previous scripts which dumped and parsed all information, but since this is only for debugging purposes this change should not be a problem.
