INTEROP: Bug report on deleteing eroutes & spi's

  I just ran into a problem of trying to delete three SPI's and having the kernel complain about it (and not remove them). It is interesting to note that the matching eroute del'ete command did not complain but did not remove the eroute I wanted gone.   The kernel 'protection' report at the end here happend due to the attempt to remove the eroute, but running the nc_radgaurd.sh del script again did not provoke the 'protection' report.
