[PATCH] drm/i915: Nuke skl_update_plane debug message from the pipe update critical section

[Maarten Lankhorst]

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.
