If an ef100_net_open() fails, ef100_net_stop() may be called without channel->rps_flow_id having been written; thus it may hold the address freed by a previous ef100_net_stop()'s call to efx_remove_filters(). This then causes a double-free when efx_remove_filters() is called again, leading to a panic. To prevent this, after freeing it, overwrite it with NULL.
