drm_fb_get_bpp_depth() likes to complain about unsupported pixel formats
but doesn't bother telling us what the format was. Also format_check()
just returns an error when it encouters an invalid format, leaving the
user scratching his head trying to figure out why addfb failed. Make
life a bit easier by using drm_get_format_name() in both places.
