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().
