    bonding: fix set_multicast_list locking

        This patch eliminates a problem (reported by lockdep) in the
    bond_set_multicast_list function.  It first reduces the locking on
    bond->lock to a simple read_lock, and second, adds netif_tx locking
    around the bonding mc_list manipulations that occur outside of the
    set_multicast_list function.

        The original problem was related to IPv6 addrconf activity.
