fork: use __vmalloc_node() for stack allocation

Browse Source 
Replace __vmalloc_node_range() by __vmalloc_node().  The last variant
requires less parameters and it uses exactly the same arguments which are
partly now hidden inside __vmalloc_node().

This change does not change any functionality.  It makes the code a bit
simpler.
