vulkan/wsi: Handle 0xFFFFFFFF special case in vk_wsi_force_swapchain_to_current_extent driconf
Handle 0xFFFFFFFF special case in vk_wsi_force_swapchain_to_current_extent driconf
Current extent can be 0xFFFFFFFF (-1) which indicates there is no current extent, and the swapchain will inherit that of which the application provides.
Check this before applying the hack.
