ath5k: use compare_ether_addr on MAC addresses instead of memcmp
Following Felix's recent patchset as an example I have replaced memcmp with
compare_ether_addr.
"Because of the constant size and guaranteed 16 bit alignment, the inline
compare_ether_addr function is much cheaper than calling memcmp."
