It shouldn't be necessary to flush the context within the driver
implementation because the old context is explicitly flushed in
_mesa_make_current before the driver code is reached. It is useful to only
have a single place that flushes the context when switching contexts to make
it easier to later implement the GL_KHR_context_flush_control extension.
