Ignat Korchagin 46f2a11cb8 af_packet: avoid erroring out after sock_init_data() in packet_create() ...

After sock_init_data() the allocated sk object is attached to the provided
sock object. On error, packet_create() frees the sk object leaving the
dangling pointer in the sock object on return. Some other code may try
to use this pointer and cause use-after-free.
