Since igt_fixture sections are processed unconditionally regardless of
which subtest has been requested, they can now emit a lot of unrelated
debug messages which can make the picture less clear. Avoid emitting
those messages from outside igt_subtest sections.
Move device close status prerequisite checks from igt_fixture sections
into subtest execution paths. For simplicity, pass any device close
errors, including those from health checks, to next sections via a
single .fd.drm data structure field.
Moreover, postpone initial device health check until first actually
selected subtest is started. In order to let that subtest skip on
unsuccessful initial health check, not fail, move the decision whether
to fail or skip on error from the health check helper to its users.
