Johannes Berg 31068288ea wifi: cfg80211: don't allow multi-BSSID in S1G 
[ Upstream commit acd3c92acc ]

In S1G beacon frames there shouldn't be multi-BSSID elements
since that's not supported, remove that to avoid a potential
integer underflow and/or misparsing the frames due to the
different length of the fixed part of the frame.

While at it, initialize non_tx_data so we don't send garbage
values to the user (even if it doesn't seem to matter now.)
