nouveau: set placement to original placement on uvmm validate.

BugLink: https://bugs.launchpad.net/bugs/2083488

commit 9c685f61722d30a22d55bb8a48f7a48bb2e19bcc upstream.

When a buffer is evicted for memory pressure or TTM evict all,
the placement is set to the eviction domain, this means the
buffer never gets revalidated on the next exec to the correct domain.

I think this should be fine to use the initial domain from the
object creation, as least with VM_BIND this won't change after
init so this should be the correct answer.
