wifi: cfg80211: correct comment about MLD ID

Browse Source 
The comment was referencing the wrong section of the documentation and
was also subtly wrong as it assumed the rules that apply when sending
probe requests directly to a nontransmitted AP. However, in that case
the response comes from the transmitting AP and the AP MLD ID will be
included.
