[PATCH net-next v6 6/8] hsr: Assign a socket for cloned skbs

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

The cloned skb does not have a socket information recorded of
the original skb. The original skb is never submitted. This means the
requested timestamp information gets lost.

Assign the socket of the original skb to the clone so the timestamp is
forwarded to the user.
