[PATCH V1 1/2] app/testpmd: fix supported RSS offload display

[Huisong Li <lihuisong@huawei.com>]

And rte_eth_dev_info.flow_type_rss_offloads is populated in terms of
RTE_ETH_RSS_* bits. If PMD sets RTE_ETH_RSS_L3_SRC_ONLY to
dev_info->flow_type_rss_offloads. testpmd will display "user defined 63"
when run 'show port info 0'. Because testpmd use flowtype_to_str()
to display the supported RSS offload of PMD. In fact, the function is
used to display flow type in FDIR commands. This patch uses the
RTE_ETH_RSS_* bits to display supported RSS offload of PMD.

Fixes: b12964f621dc ("ethdev: unification of RSS offload types")
