This patch fixes the memory leaks in memzone_autotest. Those memory leaks
lead to failures in tests from the same testing group due to out of memory
problems. With introduction of rte_memzone_free() it is now possible to
free the memzone. Fix uses this API call to make a clean after each test
case.
Fixes: ff909fe21f0a ("mem: introduce memzone freeing")
