packet : remove init_net restriction
The af_packet protocol is used by Perl to do ioctls as reported by Stephane Riviere: "Net::RawIP relies on SIOCGIFADDR et SIOCGIFHWADDR to get the IP and MAC addresses of the network interface." But in a new network namespace these ioctl fail because it is disabled for a namespace different from the init_net_ns. These two lines should not be there as af_inet and af_packet are namespace aware since a long time now. I suppose we forget to remove these lines because we sent the af_packet first, before af_inet was supported.
