We could just import the parent OPS into a local const netdevice_ops
instance, that's how we handle this everywhere else.

To prevent changes in the parent being lost in the rndis driver we can
encapsulate the ops assignments into a macro used by both.  Taking the
set_multicast_list as an arg.

Alternatively the parent can provide a hook function pointer for this
multicast operation, which the parent runs when non-NULL.
