inet_diag: Remove indirect sizeof from inet diag handlers
There's an info_size value stored on inet_diag_handler, but for existing code this value is effectively constant, so just use sizeof(struct tcp_info) where required. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
