TTM assumes an error condition from man->func->get_node() means that
something went horribly wrong, and causes it to bail.
The driver is supposed to return 0, and leave mm_node == NULL to
signal that it couldn't allocate any memory.

This is required on nv50 as we need to be able to have more precise control
over physical VRAM allocations to avoid buffer corruption when using
buffers of mixed memory types.
This removes some nasty overallocation/alignment that we were previously
using to "control" this problem.
