Raja Subramanian d863b45dc1 Remove Head field from ExtPacket structure. (#662) ...

* Remove `Head` field from `ExtPacket` structure.

Although we do not intend to, but if packets get out-of-order
in the forwarding path (maybe reading in multiple goroutines
or using some worker pool to distribute packets), the `Head`
indicator could lead to wrong behaviour. It is possible that
at the receiver, the order is
- Seq Num N, Head = true
- N + 1, Head = true

If the forwarding path sees `N + 1` first, the Head flag
when it sees `N` packet is incorrect and will lead to incorrect
behaviour.

The alternative check is very simple. So, remove `Head` flag.

* Remove unused field
