The purpose of iterating a vmlist is finding vm area with specific
virtual address. find_vm_area() is provided for this purpose
and more efficient, because it uses a rbtree.
So change it.

You no longer take the 'vmlist_lock'. This is safe, because...?

As Bob mentioned, find_vm_area() hold a 'vmap_area_lock' during
searching a area.
When we hold a 'vmap_area_lock', area can't be removed.
So this change is safe.

Thanks.
