drm/i915: use the correct obj when preparing the sprite plane

Commit "drm/i915: create a prepare phase for sprite plane updates"
changed the old_obj pointer we use when committing sprite planes,
which caused a WARN() and a BUG() to be triggered. Later, commit
"drm/i915: use intel_fb_obj() macros to assign gem objects" introduced
the same problem to function intel_commit_sprite_plane().

Regression introduced by:
    commit ec82cb793c9224e0692eed904f43490cf70e8258
