The document for "lsndtime" in struct tcp_sock is placed in the wrong
place, so let's replace it in the proper place.

Fixes: d5fed5addb2b ("tcp: reorganize tcp_sock fast path variables")

The patch lgtm but this should be tagged for net-next material.

Oops......Sorry that I tagged the target branch wrong :/
I'll resend it to the net-next branch.

Thanks!
