freedreno/query: align counter snapshot locations
Some hw queries need their sample memory locations to have certain
alignment. At the moment that isn't an issue, since the only hw query
is occlusion, so all samples have the same size. But when others are
added with different sample sizes, this starts to be a problem.
All current and immediately upcoming hw queries simply need their
sample address aligned to their size, so let's use that for now.
