Johannes Berg e5b02c0961 cfg80211: scan: drop entry from hidden_list on overflow 
commit 010bfbe768f7ecc876ffba92db30432de4997e2a upstream.

If we overflow the maximum number of BSS entries and free the
new entry, drop it from any hidden_list that it may have been
added to in the code above or in cfg80211_combine_bsses().
