anv: Return correct result in EnumeratePhysicalDevices

Browse source 
If pPhysicalDevices is too small for all physical devices,
the driver must return VK_INCOMPLETE.
Since only a single physical device is supported, this is only the case
when pPhysicalDeviceCount == 0 && pPhysicalDevices != NULL.
