This prevents a memory leak in fm10k_set_ringparams. The leak occurs because we go down, change ring parameters, and then come up. However, fm10k_down on its own is not clearing the Rx rings. Since fm10k_up assumes the rings are clean we basically drop the buffers and leak a bunch of memory. Eventually we hit dirty page faults and reboot the system. This issue does not occur elsewhere because other flows that involve fm10k_down go through fm10k_close which immediately called fm10k_free_all_rx_resources which properly cleans the rings.
