staging: r8188eu: use ether_addr_equal for address comparison

We can use ether_addr_equal instead of memcmp in
update_recvframe_phyinfo_88e for comparing the incoming frame's
destination address with our local address.

Both struct ieee80211_hdr and struct eeprom_priv's mac_addr component are
2-byte aligned.
