  Log Message:
  -----------
  ofctl_parse_target: Only parse complete ofputil_flow_mod data.

When parse_ofp_flow_mod_str returns error, `fm` is incomplete and pointers
in it may be null, e.g. fm.match.flow. In this case, passing it to
ofctl_parse_flows__ may cause pointer errors because ofctl_parse_flows__
expects a valid input of type struct ofputil_flow_mod.
