This adds a test for an I/O error during snapshot deletion, and maybe more importantly, for how to repair the resulting image. If the snapshot has been deleted before the error occurs, the only negative result will be leaked clusters -- and those should be repairable with qemu-img check -r leaks.

This means waste of disk space, but no harm to data.
