We shouldn't use the contents of data.display to determine which pipes
to run subtests on since this structure is initialized in an igt_fixture
and won't contain any useful data when enumerating subtests (i.e.,
--list-subtests won't return anything).

Instead, just assume we have three pipes in the main loop and ensure
that each subtest will skip if we don't really have that many.
