    This fix makes sure the ast_channel hangs up correctly when the dialog's PENDING_BYE flag is set.
    
    When the pending bye flag is used, it is possible that the dialog will terminate
    and leave the sip_pvt->owner channel up.  This is because we never hangup the
    ast_channel after sending the SIP_BYE request.  When we receive the response for
    the SIP_BYE we set need_destroy which we would expect to destroy the dialog on the
    next do_monitor loop, but this is not the case.  The dialog will only be destroyed
    once the owner is hungup even with the need_destroy flag set.  This patch sets the
    softhangup flag on the ast_channel when a SIP_BYE request is sent as a result of the
    pending bye flag.
