radv: Fix vkCmdCopyQueryResults -> vkCmdResetPool hazard.
The Vulkan specification states:
> Query commands, for the same query and submitted to the same queue,
> execute in their entirety in submission order, relative to each other. In
> effect there is an implicit execution dependency from each such query
> command to all query commands previously submitted to the same queue.
Fixes dEQP-VK.query_pool.statistics_query.reset_after_copy.*
