SCCP SCOC: Ensure user primitive msgb->l2h always poinst to tail
In case there is no user data in a CONNECT.conf primitive (or other CO
primitives), we must make sure that msgb->l2h = msgb->tail so that the
SCCP User can use msgb_l2len(msg) == 0 as indicator to verify if user
data is present or not.
