[PATCH] nouveau/ttm: fix tiled system memory with Maxwell

[Alexandre Courbot]

Add Maxwell to the switch statement that sets node->memtype, otherwise
all tiling information is ignored for buffers in system memory.

While we are at it, make that switch statement explicitly complain the
next time we meet a non-handled card family.
