app/testpmd: fix RSS by setting mq_mode
app/testpmd: fix RSS by setting mq_mode

The mq_mode was not set when rxq is > 0; it's defaulted to ETH_MQ_RX_NONE.
As a result, RSS remains inactive. The fix is to set mq_mode to ETH_MQ_RX_RSS
when hf is non-zero.

This bug was introduced by commit 243db2ddee3094a2cb39fdd4b17e26df4e7735e1
