Subject: [PATCH] drm/i915/selftests: Add some missing error propagation
Git-commit: 79d0150d2d983a4f6efee676cea06027f586fcd0
Patch-mainline: v6.4-rc6
Alt-commit: 412fa1f097f48c8c1321806dd25e46618e0da147
References: git-fixes

Add some missing error propagation in live_parallel_switch.

To avoid needlessly burdening the various backport processes, note I am
not marking it as a fix against any patches and not copying stable since
it is debug/selftests only code.
