mac80211: tweak mac address allocation
Apparently there are some broken devices out there that have the local bit already set in the factory MAC address. Move the | 0x2 over to the other side of the xor operation to fix this without affecting devices with proper addresses. Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 37269
