Remove false positive unknown chain member warnings

These warnings would be printed when any struct not explicitely looked for
appeared in the pNext chain of GetPhysicalDeviceSurfaceCapabilities2KHR's
in the emulation of VK_EXT_surface_maintenance1, which only looked for a
small subset of the possible structs that could be in the chain.
