i965: Fix memory leaks in brw_upload_cs_work_groups_surface().
This was taking a reference to the 64kB upload buffer and never
returning it, leaking a reference each time this atom triggered.
This leaked lots of 64kB upload BOs, eventually running us out of
of VMA space. This would usually happen when using mpv to watch a
movie, after 20-40 minutes.
