[virt-viewer 3/3] Fix virt_viewer_app_activate return value

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

VirtViewerApp::activate is expected to return -1 on errors.
It calls the VirtViewerSession::open_* methods, which return FALSE
on error. However, VirtViewerApp::activate directly returns these
boolean instead of testing the returned value and properly returning
-1 on errors. This caused errors in these open methodes to be ignored.
