Description

tcp: Undo the increase in sequence number by 1 due to the FIN flag in case of a transient error.

If an error occurs while processing a TCP segment with some data and the FIN
flag, the back out of the sequence number advance does not take into account the
increase by 1 due to the FIN flag.
