Nvidia implementation of vkGetRandROutputDisplayEXT() generates X exception
when rrOutput is from different provider (or if rrOutput is just
invalid). That can happen on certain multiple GPU configurations, on which
Wine is currently unable to initialize display driver and thus create
any window.

According to Vulkan spec, vkGetRandROutputDisplayEXT is supposed to just
return VK_NULL_HANDLE if there is no corresponding VkDisplayKHR. But it is
probably better to workaround the problem to avoid long standing regression.
