vulkan: Avoid a validation error

Browse Source 
If vkAcquireNextImageKHR returns VK_SUBOPTIMAL_KHR, the semaphore
is in use, but vkDeviceWaitIdle will not wait for it, since it is
not associated with a queue. Make sure that is the case, so we don't
run into a validation error when we try vkAcquireNextImageKHR with
the same semaphore, after recreating the swap chain.

See https://github.com/KhronosGroup/Vulkan-Docs/issues/1059 for
some related discussion.

Fixes: #7079
