wifi: mac80211: correctly initialise S1G chandef for STA
When moving to the APs channel, ensure we correctly initialise the chandef
and perform the required validation. Additionally, if the AP is beaconing on a
2MHz primary, calculate the 2MHz primary center frequency by extracting
the sibling 1MHz primary and averaging the frequencies to find the 2MHz
primary center frequency.
