anv: explicitly disable BT pool allocations at device init

Ported from upstream: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30841?commit_id=1f9c40a8d1b2ec3702862371af3a934e9a0c9cda The default state doesn't seem well defined (or kernel driver bug maybe?). Let's just set it to disabled on platforms where we're not using it.
