[dpdk-dev] [PATCH] l2fwd-crypto: fix behaviour of -t option

[Declan Doherty <declan.doherty@intel.com>]

passing -t 0 as a command line argument causes the application
to exit with an "invalid refresh period specified" error  which is
contrary to applications help text.

This patch removes the unnecessary option "--no-stats" and fixes the
behaviour of the -t parameter.
