[PATCH v2 4/6] app/testpmd: enhance queue count check

[David Marchand <david.marchand@redhat.com>]

Checking the number of rxq/txq in the middle of option parsing is
confusing.
Besides, a check on nb_rxq / nb_txq check already exists after
option parsing.
Only keep this latter check and make testpmd quit in this case.

Signed-off-by: David Marchand <david.marchand@redhat.com>

Changes since v1:
- moved the check and termination out of argument parsing,
