mesa: check for dummy renderbuffer in _mesa_FramebufferRenderbufferEXT()

Fixes a failed assertion when a renderbuffer ID that was gen'd but not
previously bound was passed to glFramebufferRenderbuffer().  Generate
the same error that NVIDIA does.

NOTE: This is a candidate for the 7.9 and 7.10 branches.
(cherry picked from commit dd973cd9e81abf1c0bc1880c7905f3277d4361a0)
