    drm/i915/selftests: Add some missing error propagation
    
    [ Upstream commit 79d0150d2d983a4f6efee676cea06027f586fcd0 ]
    
    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.
