[PATCH v2 0/7] Fix rtp when processing OOB workarounds

[Lucas De Marchi]

Patch 5 is a quick fix for processing rtp entries that is used by
the OOB WAs, i.e. WAs without an action associated. Thanks Gustavo for
spotting the issue while browsing the code. This can be applied
independently of the rest.

Last patch is a refactor so it's more obvious what it's doing.

The rest of the patches improve the kunit tests so the bug described
would have been caught. Now the logic used by OOB WAs is also covered by
the kunit tests. If those tests are executed without the fix provided in
patch 5, the following errors appear:

	# xe_rtp_process_tests: EXPECTATION FAILED at drivers/gpu/drm/xe/tests/xe_rtp_test.c:494
	Expected active == param->expected_active, but

With the fix, all of them pass.

v2:
  - Fix build due to missing change
  - Add tests for xe_rtp_process()
