* Don't override detailed error string with generic one
* Set the D-Bus reply error in case of jackctl_server_stop() failure
* Set the D-Bus reply error in case of jack_controller_patchbay_init() failure
* Don't set the D-Bus reply error in case of jack_deactivate() failure because
this failure does not cause jack_controller_stop_server() failure and thus
will cause memory leak.
Even if client is subscribed to jack server start/stop signals,
there is a timeframe between jack server stop and signal delivery.
In this frame, calls that require started server will fail.
This is part of normal operation and should not be treated as real error.
With this changeset, error is reported through dbus but no error is printed
in the log file
