sock: free skb in skb_complete_tx_timestamp on error
[ Upstream commit 35b99dffc3f710cafceee6c8c6ac6a98eb2cb4bf ]
skb_complete_tx_timestamp must ingest the skb it is passed. Call
kfree_skb if the skb cannot be enqueued.
Fixes: b245be1f4db1 ("net-timestamp: no-payload only sysctl")
Fixes: 9ac25fc06375 ("net: fix socket refcounting in skb_complete_tx_timestamp()")
