There are a couple of failure paths here. How does the caller of
EGLImageTargetRenderbufferStorage detect and propagate failures? It
seems like there should be some _mesa_error calls in here.
Should this function also be under a "#if FEATURE_OES_EGL_image" block?

Same comments as for intel_image_target_renderbuffer_storage.
