Return different error code for the guard page layout violation.

On KERN_NO_SPACE error, as it is returned now, vm_map_find() continues
the loop searching for the suitable range for the requested mapping
with specific alignment.  Since the vm_map_findspace() succesfully
finds the same place, the loop never ends.

The errors returned from vm_map_stack() completely repeat the behavior
of vm_map_insert() now, as suggested by Alan.
