[ns] stop session

[Sencun Zhu <szhu1@ise.gmu.edu>]

Hello, all, I met a problem when trying to stop and delete srm agent.
what I did is below:

    $node   leave-group $srm $group
    $ns     detach-agent $node  $srm
    $srm    delete
    delete   $srm

however, the error is like:

ns: _o187 send-session: invalid command name "_o187"
    while executing
"_o187 send-session"

This looks the session message is not stopped, how can I really stop it
and delete the srm agent?

thank you.
