d2d1: Fix double free bug when d2d_geometry_sink_Close fails.

Browse source 
geometry->fill.bezier_vertices was being freed on the failed path in
d2d_geometry_sink_Close and then again when the path geometry was
released (in d2d_geometry_cleanup).

By setting it to NULL after freeing it initially, all other calls
to free it are a no-op.
