l4p/tcp_ofo: fix handling out-of-order packets
Problems are:
1. ofodb could not be assigned directly, as direct assignment does not
copy the mbuf pointer area belonging to it.
2. _ofo_insert_new and _ofo_insert_right doesn't remove overlap correctly.
3. _ofo_insert_new insert new db in wrong position.
4. rx_ofo_reduce sets wrong seq, and would insert overlapped data into
rx queue.
5. _ofo_compact may miss compacting some ofodbs and doesn't update partly
moved ofodb correctly.
