vulkan/wsi: handle queue families properly for non-concurrent sharing mode.
"queueFamilyIndexCount is the number of queue families having access to the image(s) of the swapchain when imageSharingMode is VK_SHARING_MODE_CONCURRENT. pQueueFamilyIndices is a pointer to an array of queue family indices having access to the images(s) of the swapchain when imageSharingMode is VK_SHARING_MODE_CONCURRENT." If the type isn't concurrent, don't attempt to access the arrays. dEQP-VK.wsi.xlib.swapchain.create.exclusive_nonzero_queues on lavapipe.
