Stop policy timer before invoking session destructor

Browse Source 
The CDM session was being destroyed before the policy timer was stopped
and before the session was removed from a list of active sessions. This
allowed race conditions, where the policy timer would try to evaluate
policy for a closed session. This led to segfaults.
