Kalle Valo 125c7c392f atmodem: fix crash during context deactivation 
Ofono either crashed or busy looped with my Huawei E1552 3G modem when I
tried to deactivate GPRS context. The reason was that gcd->chat was
unreferenced already in setup_ppp() but the chat was still accessed
later in at_gprs_deactivate_primary().

To fix the problem, change the logic instead to suspend chat session
for PPP and resume when PPP has disconnected. Now it doesn't crash
anymore.

Deactivation still doesn't work properly with Huawei E1552, and most
probably with other Huawei modems, because the modem hangs up the chat
line after PPP deactivation. This needs to be fixed separately. The
workaround is to reboot the modem, for example physically unplug and plug
it in again.

Kalle Valo bf7243eda4 atmodem: refactor context deactivation 
The old way of using CGACT is no longer needed.  It is enough
that we shutdown PPP. Recommended by Denis.

Denis Kenzior b5f81f4012 Fix: For now calling g_at_chat_unref is fine 
Same as g_at_chat_shutdown in this case
