tcp: make TCP_INFO more consistent tcp_get_info() has to lock the socket, so lets lock it for an extended critical section, so that various fields have consistent values. This solves an annoying issue that some applications reported when multiple counters are updated during one particular rx/rx event, and TCP_INFO was called from another cpu.
