vbo: Remove the VBO_SAVE_FALLBACK flag.

On finishing a display list playback the VBO_SAVE_FALLBACK bit
is still kept in vbo_save_context::replay_flags. But examining
replay_flags and the display list flags that feed this value
the corresponding bit is never set these days anymore.
So, since it is nowhere set or checked, we can safely remove it.
