Subject: [PATCH 03/10] security: fix documentation for the socket_post_create hook

This patch slightly fixes the documentation for the
socket_post_create hook. The documentation states that
i_security field is accessible through inode field of socket
structure (i.e., 'sock->inode->i_security'). There is no inode
field in the socket structure. The i_security field is accessible
through SOCK_INODE macro. The patch updates the documentation
to reflect this.
