nl80211/cfg80211: Make addition of new sinfo fields safer
Add a comment pointing out the use of enum station_info_flags for all new struct station_info fields. In addition, memset the sinfo buffer to zero before use on all paths in the current tree to avoid leaving uninitialized pointers in the data.
