For some drivers which can not support the configured RSS hash functions,
the thread reports 'invalid rss_hf' when doing device configure.

For example, i40e driver can not support 'RTE_ETH_RSS_IPV4',
'RTE_ETH_RSS_IPV6' and 'RTE_ETH_RSS_NONFRAG_IPV6_OTHER', thus it can not
run successfully in test-pipeline with XL710 NIC and reports the issue:
-------------------------------------------------------------
Ethdev port_id=0 invalid rss_hf: 0xa38c, valid value: 0x7ef8
PANIC in app_init_ports():
Cannot init NIC port 0 (-22)
-------------------------------------------------------------

To fix this, referring to l3fwd operation, adjust the 'rss_hf' based on
device capability and just report a warning.

This treatment is very common.
