From: Huisong Li <lihuisong@huawei.com>

Currently, when starting testpmd application without '--disable-rss' and
the number of Rx queue configured is greater than 1, ETH_MQ_RX_RSS flag
is set in port->dev_conf.rxmode.mq_mode in testpmd application, and
DEV_RX_OFFLOAD_RSS_HASH flag is set in rx_offloads
(dev->data->dev_conf.rxmode.offloads) according to the ETH_MQ_RX_RSS
flag of rxmode.mq_mode in PMD drivers.

However, DEV_RX_OFFLOAD_RSS_HASH is not set to rx_offloads maintained
in testpmd application, this will cause the inconsistent problem that
rx_offloads is different for testpmd and PMD drivers.

v1 -> v2: add check if PMD support DEV_RX_OFFLOAD_RSS_HASH before
	  setting it.
