[Cogl] [PATCH 2/2] Bind the framebuffer before calling glDiscardFramebuffer

[Neil Roberts]

This patch just adds a call to _cogl_framebuffer_flush_state to ensure
the correct framebuffer is bound before discarding its buffers.
Previously it would presumably just discard the buffers of whatever
framebuffer happened to be used last.
