slub: remove invalid reference to list iterator variable
If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure. Thus this value should not be used after
the end of the iterator. The patch replaces s->name by al->name, which is
referenced nearby.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
