[dpdk-stable] [PATCH] app/testpmd: fix flow rules list after port stop

[Gregory Etelson]

According to current RTE API, port flow rules must not be kept
after port stop.

Testpmd did not flush port flow rules after `port stop' command was
called. As the result, after the port was restarted, it showed bogus
flow rules.

Fixes: ce8d561418d4 ("app/testpmd: add port configuration settings")
