Perftest: Fix specifying QP number 1 in non bw test

Original message says that multiple QPs is only available for bw test,
but even if user uses `-q 1`, it would still fail and print error, which
doesn't match with the message. Change the logic to check if user
specified more than 2 QPs for non-bw tests.
