[PATCH v2 4/8] app/testpmd: reconfigure forwarding after changing portlist

[Bernard Iremonger <bernard.iremonger@intel.com>]

Set nb_fwd_ports to zero on quit.
Check portlist has been set before displaying forwarding configuration.

Fixes: d3a274ce9dee ("app/testpmd: handle SIGINT and SIGTERM")
Fixes: af75078fece3 ("first public release")
