[lttng-dev] [LTTNG-TOOLS PATCH 2/9] Explicitely stop the session on lttng destroy

[Julien Desfossez]

This is going to be useful for the upcoming feature that checks and
eventually displays the amount of lost packets/discarded events.

If we don't do that, more events might be lost/discarded between the
"lttng destroy" command and the time the trace is actually stopped.
