[dpdk-stable] [PATCH] tests/cmdline: fix memory leaks

[ohilyard@iol.unh.edu]

From: Owen Hilyard <ohilyard@iol.unh.edu>

Fixes for a few memory leaks in the cmdline_autotest unit test.

All of the leaks were related to not freeing the commandline struct
after testing had completed.

Fixes: dbb860e03e ("cmdline: tests")
