drm/nouveau: fix init table handlers to return proper error codes

We really want to be able to distinguish between INIT_DONE and an actual
error sometimes.  This commit fixes up several lazy "return 0;" to be
actual error codes, and explicitly reserves "0" as "success, but stop
parsing this table".
