ip: constify ip_build_and_send_pkt() socket argument
This function is used to build and send SYNACK packets, possibly on behalf of unlocked listener socket. Make sure we did not miss a write by making this socket const. We no longer can use ip_select_ident() and have to either set iph->id to 0 or directly call __ip_select_ident() Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
