drm/i915: Update dbuf slices only with full modeset



During full modeset, global state(i.e dev_priv) is protected
by locking the crtcs in state, otherwise global state is not
serialized. Also if it is not a full modeset, we anyway
don't need to change DBuf slice configuration as Pipe configuration
doesn't change.
