Pau Espin 226b4bc58a sgsn: Fix echo timer not started upon first pdp ctx created
Commit 176a4d2f33865a5c0433f8679f5e68f209d7b874 moved echo timer related
code to its own function but did some mistakes when moving the logic
from several places into its own function. As a result, echo timer was
only enabled after the 2nd pdp ctx was created, instead of the expected
1st.
First, let's be consistent and always call the function *after* changing
state, since that's what the function expects. This fixes the issue.

Finally make the logic in the function more intuitive by checking in the
if clause the only case where actually the echo timer should be enabled:
Only if policy specifies so and we have at least 1 pdp ctx against that ggsn.

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.
