mgcp: simplify getting msgb tail in mgcp_msg_terminate_nul()
The current statement: msg->l2h + msgb_l2len(msg) looks as follows, if we expand the msgb_l2len(): msg->l2h + msgb->tail - msg->l2h so this is basically equal to msgb->tail alone. Change-Id: I4f4b0f792bbeef94a5449c4a5843628a703a3d54 Related: CID#272990
