fonts: Ignore re-initialization of fallback glyphs from the server.

If the client finds that the server re-initializes a cached path/image,
we consider this an error and invalid data. But since we might
initialize a glyph using a fallback on the client, and receive the
correct version from the server later, this is not longer true.
