If station sends association request with invalid size HE capabilities
IE, current implementation will find the error and clear WLAN_STA_HE bit
of sta->flags. While in this case, AP still sends association response
with HE related IEs, which may confuse station that thay can connect in
HE mode. Before sending association response, it shall check whether
WLAN_STA_HE bit of sta->flags is set to decide if HE related IEs can be
