drm/i915/fbdev: Use the PLANE_HAS_FENCE flags from the time of pinning 

Use the information about the fence state from the time of pinning to
determine if the fbdev writes are going through a fence. This avoids any
confusion in cases where the fence may appear or disappear unconnected
to the use by fbdev.
