[dpdk-dev] [PATCH] app/test: fix mempool test failure on FreeBSD

[Dmitry Kozlyuk <dkozlyuk@oss.nvidia.com>]

FreeBSD EAL does not implement rte_mem_virt2iova()
that was used in mempool_autotest, causing it to fail:

    EAL: Test assert test_mempool_flag_non_io_unset_when_populated_with_valid_iova
    line 781 failed: Cannot get IOVA
    test failed at test_mempool():1030
    Test Failed

Change unit test to use rte_memzone_reserve() to allocate memory,
which allows to obtain IOVA directly.

Bugzilla ID: 863
Fixes: 11541c5c81dd ("mempool: add non-IO flag")
