libs/vkd3d: Avoid vkCmdCopyQueryPoolResults() for not issued queries.

The Vulkan spec states:

  * "If the query does not become available in a finite amount of time
    (e.g.  due to not issuing a query since the last reset), a
    VK_ERROR_DEVICE_LOST error may occur."

  * "If queries will never finish (e.g. due to being reset but not
    issued), then vkGetQueryPoolResults may not return in finite time."
