mwifiex: Copy scan_cfg_out->specific_bssid for proper alignment

MAC addresses passed into is_zero_ether_addr() must be two byte aligned.
scan_cfg_out->specific_bssid is not two byte aligned which is why we
make a temporary copy and pass that copy into is_zero_ether_addr().

This previously caused misaligned exceptions on the ARC 750D platform.
