app/testpmd: fix displaying Rx/Tx queues information

Currently, the information of Rx/Tx queues from PMD driver is not
displayed exactly in the rxtx_config_display function. Because
"ports[pid].rx_conf" and "ports[pid].tx_conf" maintained in testpmd
application may be not the value actually used by PMD driver. For
instance, user does not set a field, but PMD driver has to use the
default value.

This patch fixes rxtx_config_display so that the information of Rx/Tx
queues can be really displayed for the PMD driver that implement
.rxq_info_get and .txq_info_get ops callback function.

Fixes: d44f8a485f5d ("app/testpmd: enable per queue configure")
