[PULL 4/7] audio/jack: do not remove ports when finishing

[Gerd Hoffmann]

From: Geoffrey McRae <geoff@hostfission.com>

This fixes a hang when there is a communications issue with the JACK
server. Simply closing the connection is enough to completely clean up
and as such we do not need to remove the ports first. As JACK uses a
socket based protocol that relies on the `select` call, if there is a
communication breakdown with the server the client library waits
forever for a response to the unregister request.
