target/smp: use a struct list_head to hold the smp targets

Browse Source 
Instead of reinventing a simply linked list, reuse the list helper
for the list of targets in a smp cluster.
Using the existing helper, that implements a double linked list,
makes trivial going through the list in reverse order.
