Revert "selinux: add a skb_owned_by() hook"
This reverts commit ca10b9e9a8ca7342ee07065289cbe74ac128c169. No longer needed after commit eb8895debe1baba41fcb62c78a16f0c63c21662a ("tcp: tcp_make_synack() should use sock_wmalloc") When under SYNFLOOD, we build lot of SYNACK and hit false sharing because of multiple modifications done on sk_listener->sk_wmem_alloc Since tcp_make_synack() uses sock_wmalloc(), there is no need to call skb_set_owner_w() again, as this adds two atomic operations.
