If we return due to an unknown chipset in drivers/gpu/drm/nouveau/nv20_graph.c:nv20_graph_create() we'll leak the memory allocated to 'pgraph'.
This patch should fix the leak and it also disambiguates the "PGRAPH: unknown chipset\n" error message - it's nice to be able to tell which branch created the error which is impossible if the error messages are 100% identical.

Don't have the hardware, so compile tested only.
