[Intel-gfx] [PATCH 07/23] drm: Make the fb refcount handover less magic

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Instead of assigning the plane->fb pointer and clearing the fb pointer
to hand over the reference, let's just do it by grabbing another
referece for plane->fb and let fb keep its original one.
