Return an error if apiVersion is 1.1+.

The Vulkan loader is supposed to check the requested apiVersion and return
VK_ERROR_INCOMPATIBLE_DRIVER if the requested version is not supported.  The
loader wasn't performing the check, nor returning the error.  A log message is
also issued, explaining why the application failed to create an instance.

Bug: 38040828
Test: Modify cube to use 1.0 or 1.1 and ensure proper return value.
