[Nouveau] [PATCH] drm/nouveau: Do not show an error if the TMDS table pointer is invalid

[Albert Pool]

Optimus cards with no outputs trigger this message (NVD7, for example)
This commit changes the warning into an informational message.
The return value of the function is not used, so I left it at -EINVAL.
