If a subtest fails, cleanup_crtc() never gets called.  Currently that
also causes igt_pipe_crc_free() to never be called, leading all
subsequent subtests to also fail with -EBUSY at igt_pipe_crc_new().
Move the calls to igt_pipe_crc_{new,free} into igt_main so that
we don't need to worry about closing and reopening the CRC
filedescriptor for each subtest.

IIRC we can't call them at init because when you call igt_pipe_crc_new()
the pipe->port mapping has to be properly set up so that the auto crc
source will know what to do.

The subtest failure case is the reason why at the start of every subtest
we call igt_pipe_crc_free() before calling igt_pipe_crc_new(). Are you
saying that's not working as intended?

Right, you're working on a fresh test_data structure for each call of
run_test(), so you've already lost the test_data->pipe_crc pointer that
you're trying to check for NULL there.

I guess the right fix is to move the pipe_crc pointer up into data_t
rather than test_data_t?

I guess just kill test_data_t and shovel everything into data_t. I don't
remember why the test_data_t came to be there, but I don't think it
serves any purpose anymore.

Also just run igts with piglit. That runs every subtest separately which
helps a lot for such issues. Running all the tests is kinda just the
quick&hacky versions if you're wreaking havoc with a single tests.

Otoh for that I just run one subtest through the cmdline switch. So not
sure how much we should bother here really ...
