Pau Espin da69ced353 sgsn_libgtp: Avoid ps-paging MS on GMM Suspended state 
The MS notifies movement to GMM SUSPEND state because it is for instance
handling a call and cannot use PDCH anymore. Once it releases the TCH it
will ASAP move to either dedicated mode or trigger RAU, which means it
will get out of SUSPEND state. So it doesn't make sense to try paging
the MS when in that state.

About OsmoSGSN
==============

OsmoSGSN originated from the OpenBSC project, as a separate program within
openbsc.git. In 2017, OpenBSC was split in separate repositories, and hence
OsmoSGSN was given its own separate git repository.

OsmoSGSN exposes
- GSUP towards OsmoHLR (or a MAP proxy);
- GTP towards a GGSN (e.g. OsmoGGSN);
- Gb towards a BSS (e.g. OsmoPCU);
- IuPS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G data;
- The Osmocom typical telnet VTY and CTRL interfaces.
