lsm: Remove the socket_post_accept() hook
The socket_post_accept() hook is not currently used by any in-tree modules and its existence continues to cause problems by confusing people about what can be safely accomplished using this hook. If a legitimate need for this hook arises in the future it can always be reintroduced. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
