Looks OK.
Following note is aside from the patch.
Might be beneficial (in some rare cases) to add bailout recovery with
goto's in test_memzone_basic()
Just in case one of the rte_memzone_reserve() we should not make return -1,
but instead a goto to below section where we call rte_memzone_free().
This way we would be able to free only the allocated memzones and prevent
leaking out those memzones to other tests.
