net: l2: ieee802154: AR shall be provided in association requests

Browse source 
The spec clearly states: "association requests shall set the AR bit".

Even though Zephyr can currently only implement RFD devices which are
not expected to support incoming association requests, because this MAC
command is actually processed until being voluntarily ignored, let's
ensure the expected "ar" value is right to avoid failing because of a
wrong reason.
