mac80211: fix alignment issue with compare_ether_addr()
This addresses an alignment issue with compare_ether_addr(). The addresses passed to compare_ether_addr should be two bytes aligned. It may function properly in x86 platform. However may not work properly on IA-64 or ARM processor. This also fixes a typo in mlme.c where the sk_buff struct name is incorect. Though sizeof() works for any incorrect structure pointer name as its just a pointer length that we want, lets just fix it.
