[PATCH] nouveau: safen up nouveau_device list usage against concurrent access

Here's a test program I just whipped up that demonstrates (some of) the issues in the old code. This segfaults in either nouveau_bo_wrap or nouveau_bo_new, or sometimes nouveau_bo_wrap fails to find the handle. With the patch, it hasn't failed yet. Ben -- review please? (Or someone else...)
