ofp-errors: Use OFPERR_OFPBRC_BAD_PORT

Browse Source 
* In the case of OpenFlow 1.2+ OFPERR_OFPBRC_BAD_PORT is defined
  in the specification and seems to be the most appropriate error
  to use when an invalid port is encountered in a Packet Out request.

* In the case of OpenFlow 1.0 and 1.1 no appropriate error message
  seems to exist. Perhaps because an invalid port is not possible?
  I'm unsure.

  In any case, make use of a non-standard error code (1,514).
  This was formerly known as OFPERR_NXBRC_BAD_IN_PORT but
  has been rolled into OFPERR_NXBRC_BAD_IN_PORT to allow the
  latter to be used without concern for the prevailing Open Flow version.
