mac80211: fix MAC address allocations when local bit set on base addr
Testing with hwsim reveals two problems: 1. phyX/addresses has two addresses and mac80211_get_addr keeps returning the last one when asked for more; 2. The base address has the local bit set and the operation unsets it. Fix both. Fixes: 866790fd827cb0187353cdf484eb46a9b38fb6ba Reported-by: Zero_Chaos Signed-off-by: Paul Fertser <fercerpav@gmail.com>
