[dpdk-dev] [PATCH] test/mempool: fix false positive test result

[Olivier Matz <olivier.matz@6wind.com>]

The ret variable, initialized to -1, is changed to 0 during the test,
making the test successful in some cases where it should return a
failure.

Fix this by always using the GOTO_ERR() macro that sets the ret
variable before doing the goto.

Fixes: 923ceaeac140 ("test/mempool: add unit test cases")
