After locks rework [1], ieee80211_start_radar_detection() function is no
longer acquiring any lock as such explicitly. Hence, it is not unlocking
anything as well. However, label "out_unlock" is still used which creates
confusion. Also, now there is no need of goto label as such.

Get rid of the goto logic and use direct return statements.
