drm: Populate fb->dev from drm_helper_mode_fill_fb_struct()
Populating fb->dev before drm_framebuffer_init() allows us to use
fb->dev already while validating the framebuffer. Let's have
drm_helper_mode_fill_fb_struct() do that for us.
Also make drm_framebuffer_init() warn us if a different device
pointer is passed to it than was passed to
drm_helper_mode_fill_fb_struct().
v2: Reject fbs with invalid fb->dev (Laurent)
