net: l2: ieee802154: Change the hardware filters while associating

Browse source 
During an association, the peer we are trying to connect to will send us
an association response frame with the destination PAN ID set to the PAN
ID we try to join. If we do not update the hardware address filters
beforehands, it is likely that the hardware will just discard the
response and the association will fail.
