[dpdk-stable] [PATCH] test/pmd_perf: change the way to drain the port

If the port has received less than ``pkt_per_port`` packets (for
example, the port has missed some packets), the test is in an infinite
loop.
Instead of expecting a number of packet to receive, let the port to be
drained by itself. If no more packets are received, the test can
continue.
Fixes: 002ade70e933 ("app/test: measure cycles per packet in Rx/Tx")
