4261109 by Guy Harris (guy@xxxxxxxxxxxx):

    Don't return an error string for NO_INTERFACES_FOUND.
    
    Most callers of capture_interface_list() don't expect an error string
    for NO_INTERFACES_FOUND, because that's not really an error, it's just a
    statement of face (and perhaps an error of 0 should be returned), so
    they don't bother freeing the error string, causing a leak.
    
    Instead, have the one place that *did* expect it to return an error
    string just put "No interfaces found" itself.
    
    Also, have that place not check for an error string if interfaces *were*
    found, as no error code or string is returned in that case.
