batman-adv: Use default throughput value on cfg80211 error

Browse Source 
commit 3f3f87325dcb3c201076c81490f4da91ad4c09fc upstream.

A wifi interface should never be handled like an ethernet devices. The
parser of the cfg80211 output must therefore skip the ethtool code when
cfg80211_get_station returned an error.
