Avoid enqueueing the same ISeq twice

by a race condition by multiple Ractors.

Atmically incrementing body->total_calls may have its own cost, so for
now we intentionally leave the unreliable total_calls. So we allow an
ISeq to be never pushed when you use multiple Ractors. However, if you
enqueue a single ccan node twice, get_from_list loops infinitely. Thus
this patch takes care of such a situation.
