sfc: fix a double-free bug in efx_probe_filters
In efx_probe_filters, the channel->rps_flow_id is freed in a
efx_for_each_channel marco when success equals to 0.
However, after the following call chain:
ef100_net_open
|-> efx_probe_filters
|-> ef100_net_stop
|-> efx_remove_filters
The channel->rps_flow_id is freed again in the efx_for_each_channel of
efx_remove_filters, triggering a double-free bug.
