net: clear skb->tstamp in bridge forwarding path

Browse Source 
[ Upstream commit 41d1c8839e ]

Matteo reported forwarding issues inside the linux bridge,
if the enslaved interfaces use the fq qdisc.

Similar to commit 8203e2d844 ("net: clear skb->tstamp in
forwarding paths"), we need to clear the tstamp field in
the bridge forwarding path.

Fixes: 80b14dee2b ("net: Add a new socket option for a future transmit time.")
Fixes: fb420d5d91 ("tcp/fq: move back to CLOCK_MONOTONIC")
