  When input queue id is invalid, it will lead to
Segmentation fault, like:

dpdk-testpmd -a 0000:01:00.0 -- -i
testpmd> show port 0 txq/rxq 99 desc 0 status
Segmentation fault

dpdk-testpmd -a 0000:01:00.0 -- -i
testpmd> show port 0 rxq 99 desc used count
Segmentation fault

This patch fixes it.

Fixes: fae9aa717d6c ("app/testpmd: support checking descriptor status")
Fixes: 3f9acb5c83bb ("ethdev: avoid non-dataplane checks in Rx queue count")
Cc: stable@dpdk.org
