rtlwifi: use ether_addr_equal_64bits
Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array. The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h and rtl_mac defined in drivers/net/wireless/rtlwifi/wifi.h This was done using Coccinelle (http://coccinelle.lip6.fr/).
