selftests/bpf: test_xsk: Fix __testapp_validate_traffic()'s return value

__testapp_validate_traffic is supposed to return an integer value that
tells if the test passed (0), failed (-1) or was skiped (2). It actually
returns a boolean in the end. This doesn't harm when the test is
successful but can lead to misinterpretation in case of failure as 1
will be returned instead of -1.

Return TEST_FAILURE (-1) in case of failure, TEST_PASS (0) otherwise.
