app/testpmd: configure RSS without restart

Browse Source 
The function cmd_config_rss_parsed() associated with the command
"port config rss all" required to first stop all ports, in order to
then entirely re-configure all ports with the new RSS hash computation
parameters.
Use now the new function rte_eth_dev_rss_hash_conf_update() that dynamically
only changes the RSS hash computation parameters of a port, without needing
to previously stop the port.
