Lorenz Bauer e3d5f12b31 bpf: Clear skb->tstamp in bpf_redirect when necessary ...

[ Upstream commit 5133498f4a ]

Redirecting a packet from ingress to egress by using bpf_redirect
breaks if the egress interface has an fq qdisc installed. This is the same
problem as fixed in 'commit 8203e2d844 ("net: clear skb->tstamp in forwarding paths")

Clear skb->tstamp when redirecting into the egress path.

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