[Mesa-stable] [PATCH] mesa: fix check for dummy renderbuffer in _mesa_FramebufferRenderbufferEXT()

[Samuel Iglesias Gonsalvez]

According to the spec:
	<renderbuffertarget> must be RENDERBUFFER and <renderbuffer>
	should be set to the name of the renderbuffer object to be
	attached to the framebuffer.  <renderbuffer> must be either
	zero or the name of an existing renderbuffer object of type
	<renderbuffertarget>, otherwise an INVALID_OPERATION error is
	generated.

This patch changes the previous returned GL_INVALID_VALUE to
GL_INVALID_OPERATION.
