…hile CloseSession is active to avoid endless loop.
Sometimes when stopping a playback Kodi crashes with a following backtrace:

After searching in the github history it came out that there was a
similar issue adressed in xbmc#728.
For some reason that piece of code got removed in
xbmc@8889fe9
(in pull request xbmc#883).
The stack trace is from the Raspberry Pi 4 machine. But I can also reproduce the issue
on my x86_64 Linux machine by adding a 1s sleep in the beginning of CdmAdapter::SetTimer.
In order to reproduce it is necessary to quickly play/stop streams.
Script attached at the end of the commit message can be used to ease the reproduction.
In my environment running the script for 1-3 minutes makes Kodi crash.
Although the root cause described in xbmc#729
was a busy loop. Right now address sanitizer reports:

The root cause of the crash is unknown as it comes directly from
libwidevine library. But it crashes when we call cdm->TimerExpired when
the session is closed. After applying mentioned commit I'm not able
to reproduce the crash anymore.
Script to reproduce the issue:
```
set -x
URI='Change it to some uri to play'
while true; do
curl -s "http://kodi:kodi@127.0.0.1:8080/jsonrpc" -H 'Content-Type: application/json' --data "{\"jsonrpc\":\"2.0\",\"method\":\"Player.Open\",\"params\":{\"item\":{\"file\":\"$URI\"}}}"
sleep $[ ($RANDOM % 70 + 30) / 10.0 ]
curl -s "http://kodi:kodi@127.0.0.1:8080/jsonrpc" -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"Player.Stop","params":{"playerid":1}}'
sleep 1
done
```
