Account for some bytes handed to the network layer prior to

dropped connections.

Such bytes were counted on some paths but not on others.  If
these bytes are to be counted in some error paths, they should
be counted in the others.  We don't know if they were actually
presented to the client.

AFAIK, this only affects mod_logio.
