[PATCH] batman-adv: clarify CFG80211 dependency

[PATCH] batman-adv: clarify CFG80211 dependency

[Arnd Bergmann]

The driver calls cfg80211_get_station, which may be part of a
module, so we must not enable BATMAN_ADV_BATMAN_V if
BATMAN_ADV=y and CFG80211=m:

net/built-in.o: In function `batadv_v_elp_get_throughput':
(text+0x5c62c): undefined reference to `cfg80211_get_station'

This clarifies the dependency to cover all combinations.
