security: drop the unused hook skb_owned_by

The skb_owned_by hook was added with the commit ca10b9e ("selinux: add a skb_owned_by() hook") and later removed when said commit was reverted. Later on, when switching to list of hooks, a field named 'skb_owned_by' was included into the security_hook_head struct, but without any users nor caller. This commit removes the said left-over field.
