mac80211: don't teardown sdata on sdata stop
Interfaces are being initialized (setup) on addition, and torn down on removal. However, p2p device is being torn down when stopped, resulting in the next p2p start operation being done on uninitialized interface. Solve it by calling ieee80211_teardown_sdata() only on interface removal (for the non-netdev case).
