radv: don't overwrite results in VkGetQueryPoolResults() when queries are not available

If the query is not available and VK_QUERY_RESULT_WAIT_BIT and
VK_QUERY_RESULT_PARTIAL_BIT are both not set, the spec doesn't
allow to modify its result.

From Vulkan spec:

"If VK_QUERY_RESULT_WAIT_BIT and VK_QUERY_RESULT_PARTIAL_BIT are
both not set then no result values are written to pData for queries
that are in the unavailable state at the time of the call, and
vkGetQueryPoolResults returns VK_NOT_READY. However, availability state
is still written to pData for those queries
if VK_QUERY_RESULT_WITH_AVAILABILITY_BIT is set."

v2:
- Move VK_NOT_READY change to next patch (Samuel Pitoiset)
