tcp: Annotate data-race around sk->sk_mark in tcp_v4_send_reset

[ Upstream commit 80fb40ba ]

This is a follow-up to 3c5b4d69 ("net: annotate data-races around
sk->sk_mark"). sk->sk_mark can be read and written without holding
the socket lock. IPv6 equivalent is already covered with READ_ONCE()
annotation in tcp_v6_send_response().

Fixes: 3c5b4d69 ("net: annotate data-races around sk->sk_mark")
