mwifiex: put multicast/broadcast packets to the same RA

For ad-hoc mode, RA is created for each peer connected. In case of multicast traffic new RA will be created for each multicast address. While processing Tx packets we have to go through this RA list. We can avoid some RA nodes by sharing same RA for both multicast and broadcast packets. Therefore "memset(0xff)" is used to treat multicast packet as broadcast one while choosing RA.
