[PATCH v2 3/6] test: fix error handling in ELF load tests

[Stephen Hemminger <stephen@networkplumber.org>]

Address related issues found during review
- Add missing TEST_ASSERT for mempool creation in test_bpf_elf_tx_load
- Initialize port variable in test_bpf_elf_rx_load to avoid undefined
  behavior in cleanup path if null_vdev_setup fails early

Fixes: cf1e03f881af ("test/bpf: add ELF loading")
Cc: stable@dpdk.org
