smp: Iterate functions through llist_for_each_entry_safe()
The IPI function llist iteration is open coded. Lets simplify this with using an llist iterator. Also we want to keep the iteration safe against possible csd.llist->next value reuse from the IPI handler. At least the block subsystem used to do such things so lets stay careful and use llist_for_each_entry_safe().
