rG5632dd45cc10: tcp: improve error handling in syncache_socket()
rG3703e1a73e0e: tcp: improve error handling in syncache_socket()
Summary

If syncache_socket() fails after calling tcp_newtcpcb(), the resources allocated during
tcp_newtcpcb() needs to be freed. Just call tcp_discardcb() to do this.

Thanks to jtl for making me aware of the issue and proposing a fix.
