drm/xen-front: Make structure fb_funcs constant 

Static structure fb_funcs, of type drm_framebuffer_funcs, is used only
when it is passed to drm_gem_fb_create_with_funcs() as its last
argument. drm_gem_fb_create_with_funcs does not modify its lst argument
(fb_funcs) and hence fb_funcs is never modified. Therefore make fb_funcs
constant to protect it from further modification.
Issue found with Coccinelle.
