Means that our circular list is pointing to itself (empty), so it all
looks like we got some list deletion between the initial list_empty()
check [1], that failed (i.e. list was not empty then), and the time we
call on to list_for_each_entry() (with a list that is now empty).
Bit puzzling, as we should have a lock when we modify the
flying_transfers list, and a deletion would have to occur outside of
that lock...
