    ui/console: unregister console from QOM tree on close

    Call object_unparent() in graphic_console_close() to remove the
    console from /backend/console[N]. This drops the QOM tree
    reference, while the initial object_new() reference keeps the
    console alive for potential reuse.

    When graphic_console_init() reuses a closed console, re-register
    it in the QOM tree.
