Subject: [PATCH 020/126] mtk: hostapd: Do not include HE capab IE if
 associated sta's HE capab IE is invalid

The parameter 'sta' passed to send_assoc_resp() might be NULL, so an
NULL check is necessary before access the 'sta'.
Only one such check was missed in this function, and this patch fixs it.
