[PATCH] vmalloc : optimization, cleanup, bugfixes

This patch does three things

1) reorder 'struct vm_struct' to speedup lookups on CPUS with small cache 
lines. The fields 'next,addr,size' should be now in the same cache line, to 
speedup lookups.

2) One minor cleanup in __get_vm_area_node()

3) Bugfixes in vmalloc_user() and vmalloc_32_user()
NULL returns from __vmalloc() and __find_vm_area() were not tested.
