Use container.HostConfig.ShmSize directly

Browse source 
It was noted[1] that container's HostConfig.ShmSize, if not set, should be
initialized to daemon default value during container creation.

In fact, it is already done in daemon.adaptContainerSettings, so we can use
value from container.HostConfig directly.
