From: Owen Hilyard <ohilyard at iol.unh.edu>
[ upstream commit ca7204b921c2f328ab1222772af40922970e7c4b ]
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")
