msg: Move the check for missing HW time stamps into caller. 

On the transmit path, the port-level code calls msg_sots_missing()
directly, but on receive this check is buried in the message layer.
With the coming addition of peer to peer one step, the ingress check
will need knowledge of the configured time stamping option.  This
patch moves the check in order to accommodate the exceptional case.
