Nouveau - Aug 2016 - [PATCH v2] drm/nouveau/gr/gf117-: mark symbols static where possible

We get 1 warning when build kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxgf117.c:222:1: warning: no previous
prototype for 'gf117_grctx_generate_main' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
so this patch marks this function with 'static'.
