If probe fails before ieee80211_register_hw() is successfully done,
ieee80211_unregister_hw() will be called anyway. This may lead to various
bugs as the implementation of ieee80211_unregister_hw() assumes that
ieee80211_register_hw() has been called.
Divide error handling section into relevant subsections, so that
ieee80211_unregister_hw() is called only when it is appropriate. Correct
the order of the calls: ieee80211_unregister_hw() should go before
plfxlc_mac_release(). Also move ieee80211_free_hw() to plfxlc_mac_release()
as it supposed to be the opposite to plfxlc_mac_alloc_hw() that calls
ieee80211_alloc_hw().
