Steps:
0. insmod several video modules.
1. Run videoinfo.
2. rmmod a random video module.
3. Run videoinfo again. Observe that the video adapter did not disappear from the list.

Doing this a few times may even trick GRUB into running an infinite loop.

In include/grub/video.h, routine grub_video_register should initialise adapter->prev to p. Otherwise grub_list_remove is unable to remove all references to the grub_video_adapter_t structure.
