drm/i915: Nuke debug messages from the pipe update critical section
printks are slow so we should not be doing them from the vblank evade critical section. These could explain why we sometimes seem to blow past our 100 usec deadline. The problem has been there ever since commit bfd16b2a23dc ("drm/i915: Make updating pipe without modeset atomic.") but it may not have been readily visible until commit e1edbd44e23b ("drm/i915: Complain if we take too long under vblank evasion.") increased our chances of noticing it.
