wifi: cfg80211: allocate memory for link_station info structure
Currently, station_info structure is passed to fill station statistics
from mac80211/drivers. After NL message send to user space for requested
station statistics, memory for station statistics is freed in cfg80211.
Therefore, memory allocation/free for link station statistics should
also happen in cfg80211 only.
Hence, allocate the memory for link_station structure for all
possible links and free in cfg80211_sinfo_release_content().
