[virt-tools-list] [virt-viewer v2] vnc: do not show error on cancel/close of auth dialog

[Victor Toso]

From: Victor Toso <me at victortoso.com>

Mainly a kiosk mode, similar to the spice fix in 6480e52f62b.

This patch saves the cancel/close state of auth dialog from
virt_viewer_auth_collect_credentials() in order to avoid an error
dialog to pop up to user in kiosk mode.

This happens due the fact that we call virt_viewer_app_disconnected()
twice:
- One with "session-cancelled" which is correct and well handled;
- The other with "session-disconnected" which is misleading as there
  was no connection at this time. This will trigger the error dialog
  with "Unable to connect to the graphic server %s".
