fix null dereference oops in nouveau.ko
This problem manifests when chipset is < nv50. In this case, pramin_init
returns NULL. mthd->data is then set to this value in shadow_method. Later,
mthd-> data is passed as a parameter to pramin_fini. The result is a kernel
oops. The attached patch takes care of that.
Best Wishes,
