tcp: do not leak non zero tstamp in output packets
Usage of skb->tstamp should remain private to TCP stack
(only set on packets on write queue, not on cloned ones)
Otherwise, packets given to loopback interface with a non null tstamp
can confuse netif_rx() / net_timestamp_check()
Other possibility would be to clear tstamp in loopback_xmit(),
as done in skb_scrub_packet()
Fixes: 740b0f1841f6 ("tcp: switch rtt estimations to usec resolution")
