[En-Nut-Discussion] net/ipout.c memory leak

[Stefan Hax]

noticed a small memory leak in ../net/ipout.c during UDP broadcast failures.

code is:
NutIpOutput(..)
{
...
                if (nif->if_type == IFT_ETHER)
                     rc = (*nif->if_output) (dev, ETHERTYPE_IP, ha, 
nb_clone);
                 else if (nif->if_type == IFT_PPP)
                     rc = (*nif->if_output) (dev, PPP_IP, 0, nb_clone);

                 if (rc == 0) {
                     NutNetBufFree(nb_clone);
                 }
...
}


sugested:
NutIpOutput(..)
{
...
                if (nif->if_type == IFT_ETHER)
                     rc = (*nif->if_output) (dev, ETHERTYPE_IP, ha, 
nb_clone);
                 else if (nif->if_type == IFT_PPP)
                     rc = (*nif->if_output) (dev, PPP_IP, 0, nb_clone);

                 if(nb_clone) {          /* <-- might be a better choice */
                     NutNetBufFree(nb_clone);
                 }
...
}
