    windows: fix terminating processes

    The neutron Windows exec call helper doesn't properly handle the
    situation in which the process that it's trying to kill was already
    terminated, in which case using wmi to fetch the process can raise
    an exception.

    This change ensures that those WMI exceptions will be properly
    handled.
