[BUG] switch server-side stream interface to close in case of abort

In pure TCP mode, there is no response analyser to switch the server-side
stream interface from INI to CLO when the output has been closed after an
abort. This caused sessions to remain indefinitely active when they were
aborted by the client during a TCP content analysis.

The proper action is to switch the stream interface to the CLO state from
INI when we have write enable and shutdown write.
