slob: fix memory corruption
Previously, it would be possible for prev->next to point to
&free_slob_pages, and thus we would try to move a list onto itself, and
bad things would happen.
It seems a bit hairy to be doing list operations with the list marker as
an entry, rather than a head, but...
this resolves the following crash:
