drm/nouveau/kms/nv04: use vzalloc for nv04_display
commit bd6e07e72f37f34535bec7eebc807e5fcfe37b43 upstream.
The struct is giant, and triggers an order-7 allocation (512K). There is
no reason for this to be kmalloc-type memory, so switch to vmalloc. This
should help loading nouveau on low-memory and/or long-running systems.
