[PATCH bpf-next v3 10/14] selftests/bpf: test_xsk: Don't exit immediately if validate_traffic fails

__testapp_validate_traffic() calls exit_with_error() on failures. This
exits the program immediately. It prevents the following tests from
running and isn't compliant with the CI.

Return TEST_FAILURE instead of calling exit_with_error().
Release the resource of the 1st thread if a failure happens between its
creation and the creation of the second thread.
