    file-operations: Don't crash after failed inhibit
    
    If gtk_application_inhibit fails, it returns a 0 cookie.  When this
    invalid value is passed to gtk_application_uninhibit, Nautilus crashes
    if glib or gtk is compiled with minimal debug checks.
    So, only call gtk_application_uninhibit if a non-zero cookie is
    returned.  Also, use the correct type for inhibit_cookie (guint).
