<pre>If either wsi_wl_init_wsi() or wsi_x11_init_wsi() fail during
anv_EnumeratePhysicalDevices(), then anv_EnumeratePhysicalDevices() fails, even
if the user did no ask for either winsys at vkCreateInstance. In particular, if
the user asked for no winsys at all, then anv_EnumeratePhysicalDevices() still
fails if winsys initialization fails.
A user requests winsys support by requesting instance extensions
VK_KHR_{wayland,xlib,xcb}_surface at time of vkCreateInstance.
We should wait until jekstrand's big vulkan/wsi series lands before fixing
this.
(I observed this bug during code review, by reading code but not running code.
So maybe this is NOTABUG.)</pre>
