[PATCH] cfg80211: Add stub for cfg80211_get_station()

[PATCH] cfg80211: Add stub for cfg80211_get_station()

[Linus Lüssing]

This allows modules using this function (currently: batman-adv) to
compile even if cfg80211 is not built at all, thus relaxing
dependencies.

Err, excuse the earlier empty email - editing mixup.

I've applied this and will send it to 4.8 so you can take advantage of
it sooner (to adjust the Kconfig dependencies, presumably).
