compat-drivers: backport mac80211 set_multicast_list() 488b366a

Synchs with next-20130326

The addition of the new mac80211 driver callback
set_multicast_list() uses the struct netdev_hw_addr_list
added as of 2.6.35. We already dealt with backporting
this collateral evolution through the changes that
went in on for the prepare_multicast() callback, as
well as porting Ethernet driver usage of this. This
is all dealt with on the patch:

patches/collateral-evolutions/network/25-multicast-list_head.patch

Reviewing that gave a quick idea of how to backport this
new callback in a similar way.

    mac80211: add driver callback for per-interface multicast filter

    Some devices have multicast filter capability for each individual
    virtual interface rather than just a global one. Add an interface
    specific driver callback allowing such drivers to configure this.
