[PATCH] uml: always disable kmalloc during shutdown
kmalloc wasn't being disabled during panic. This patch ensures that, no
matter how UML is exiting, it is disabled. This matters because part of the
cleanup is to remove the umid file, which involves readdir, which calls
malloc. This must map to libc malloc, rather than kmalloc or vmalloc.
