[PATCH wireless-next 1/8] wifi: rt2x00: start the link tuner when an interface is added

[Ho Jie Feng]

rt2x00lib_start() enables the radio before mac80211 adds the first
interface, so rt2x00link_start_tuner(), called from
rt2x00lib_enable_radio(), finds no station or AP interface and returns.

Start the link tuner again when an interface is added.
