[PATCH v2] fbdev: geode: Add the missed pci_disable_device() in gx1fb_map_video_memory()

[Chuhong Yuan]

Although gx1fb_probe() has handled the failure of gx1fb_map_video_memory()
partly, it does not call pci_disable_device() as gx1fb_map_video_memory()
calls pci_enable_device().
Add the missed function call to fix the bug.
