When closing a connection, make the nbd-fault-injector flush the socket.
Without this, the output is a bit unreliable with Python 3.

I already had a complaint that the error message in 083.out should NOT
be printing a message (whether the server is python 2 and auto-flushes,
or python 3 and needs an explicit flush, the message itself is
pointless, and the test is racy as a result). We may need to revisit
this patch when that thread is resolved.
https://lists.gnu.org/archive/html/qemu-devel/2018-08/msg01041.html
That said, I'm not opposed to this patch, if it gets iotests to be more
useful in the meantime.
