flowtop: Replace single linked list by list_head from list.h
list.h provides generic Linux-like linked list API which also supports RCU list operations. Also additionally was removed the spinlock which is not needed for RCU-list operations, for the list_del_rcu(...) case it is needed additionally call call_rcu(...) before free the flow entry. Because of full RCU support now flows are freed after grace-period (after presenter leaves RCU lock) via calling call_rcu(), because of that for the new entries we return NFCT_CB_STOLEN to tell conntrack API do not automatically free received nfct_conntrack object, it will be freed by us via call_rcu(...) therefor no need to use nfct_clone(n).
