Subject: [PATCH bpf-next v4 10/15] selftests/bpf: test_xsk: Don't exit
 immediately when gettimeofday fails

exit_with_error() is called when gettimeofday() fails. This exits the
program immediately. It prevents the following tests from being run and
isn't compliant with the CI.

Return TEST_FAILURE instead of calling exit_on_error().
