Subject: [PATCH] BUG/MEDIUM: stream: always release the stream-interface on
 abort

The cache exhibited a but in process_stream() where upon abort it is
possible to switch the stream-int's state to SI_ST_CLO without calling
si_release_endpoint(), resulting in a possibly missing ->release() for
the applet.

It should affect all other applets as well (eg: lua, spoe, peers) and
should carefully be backported to stable branches after some observation
period.
