Pull drm nouveau fixes from Dave Airlie:
"Karol found two last minute nouveau fixes, they both fix crashes, the
TTM one follows what other drivers do already, and the other is for
bailing on load on unrecognised chipsets.
- fix crash in TTM alloc fail path
- return error earlier for unknown chipsets"
