vgacon: prevent vgacon_deinit from touching the hardware for inactive consoles.
fbcon makes the (reasonable) assumption that it only needs to program the
hardware once, when fbcon_init() is called for the foreground console.
This doesn't always play well with vgacon because vgacon_deinit() is only
doing its job when the last console it owns is closed (when switching from
vgacon to fbcon, that's usually *after* fbcon_init() has set the new
mode).
Depending on the hardware this can cause the wrong framebuffer location to
be scanned out (e.g. reproduced on nv05 with the nouveau framebuffer
driver).
