libnvdimm, badrange: remove a WARN for list_empty
Now that we're reusing the badrange functions for nfit_test, and that exposes badrange injection/clearing to userspace via the DSM paths, it is plausible that a user may call the clear DSM multiple times. Since it is harmless to do so, we can remove the WARN in badrange_forget.
