But please be aware that there is at least one other bug I'm currently
investigating.

mem->mem_type seems not set yet as well if I am correct.
IIRC, I feel it's better that tbo->offset is set out of this function after
get_node successfully.
how about change to tbo->bdev->man[TTM_PL_TT].gpu_offset? since
gtt_mgr is for GTT only.
Not 100% correct either.
The problem is that sometimes a GTT MM node will be bound for a BO which is
still in VRAM (e.g. on eviction for example).
So you need to check if (&tbo->mem == mem) and only then update the tbo's
offset.
