Neels Hofmeyr aa14bac370 LU: do not always invoke sub_pres_vlr_fsm_start() 
sub_pres_vlr_fsm_start() starts the FSM, invokes the START event, and then this
FSM invariably always directly terminates when vsub->ms_not_reachable_flag ==
false.

So if it is false, there is not much use in instantiating a whole FSM instance
that just terminates again, we might as well directly issue the
parent-term-event and save some logging space.

The same condition is already in place in the vlr_proc_acc_fsm.c in
_proc_arq_vlr_node2_post_vlr() for CM Service Request and Paging Response. Now
also skip this for LU.

About OsmoMSC
=============

OsmoMSC originated from the OpenBSC project, which started as a minimalistic
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.

OsmoMSC was one of the parts split off from the old openbsc.git. Before, it was
the libmsc part of the old OsmoNITB. Since a true A interface and IuCS for 3G
support is available, OsmoMSC exists only as a separate standalone entity.

OsmoMSC exposes
- GSUP towards OsmoHLR (or a MAP proxy);
- A over IP towards a BSC (e.g. OsmoBSC);
- IuCS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G voice;
- MNCC (Mobile Network Call Control derived from GSM TS 04.07);
- SMPP 3.4 (Short Message Peer-to-Peer);
- The Osmocom typical telnet VTY and CTRL interfaces.
