Olivier Houchard fe4abe62c7 BUG/MEDIUM: connections: Don't call shutdown() if we want to disable linger.
In conn_sock_shutw(), avoid calling shutdown() if linger_risk is set. Not
doing so will result in getting sockets in TIME_WAIT for some time.
This is particularly observable with health checks.

This should be backported to 1.9.
