[RFC PATCH 6/8] mm, vmalloc: iterate vmap_area_list, instead of vmlist, in vmallocinfo()

This patch is preparing step for removing vmlist entirely. For above purpose, we change iterating a vmap_list codes to iterating a vmap_area_list. It is somewhat trivial change, but just one thing should be noticed. Using vmap_area_list in vmallocinfo() introduce ordering problem in SMP system.
