mac80211: Ensure initializing private mc_list in prepare_multicast().

Fix kernel panic by NULL pointer dereference in the context of
ieee80211_ops->prepare_multicast().

This bug was introduced by commit 22bedad3c.. ("net: convert
multicast list to list_head").

Call __hw_addr_init() in ieee80211_alloc_hw() to initialize
list_head of private device multicast list, like we do in
bond_init().
