[UML]: uml-net: don't set IFF_ALLMULTI in set_multicast_list
IFF_ALLMULTI is an indication from the network stack to the driver to disable multicast filters, drivers should never set it directly. Since the UML networking device doesn't have any filtering capabilites, it doesn't the set_multicast_list function at all, it is kept so userspace can still issue SIOCADDMULTI/SIOCDELMULTI ioctls however.
