<div class='commit-subject'>tcp: make TCP_INFO more consistent</div><div class='commit-msg'>tcp_get_info() has to lock the socket, so lets lock it
for an extended critical section, so that various fields

reported when multiple counters are updated during one
particular rx/rx event, and TCP_INFO was called from
another cpu.
