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,

Bob Gleitsmann
