nl80211/cfg80211: Make addition of new sinfo fields safer

Browse Source 
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.
