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.

This fixes a number of dEQP tests, such as:

dEQP-GLES31.functional.program_interface_query.buffer_limited_query.resource_query

It was expecting the length to be set even in the bufSize == 0 case.
Also _mesa_get_program_resourceiv does some error checking on the
resource which should probably happen even in the bufSize == 0 case as
well although there's no dEQP test for that.
