libnvdimm: clear the internal poison_list when clearing badblocks
nvdimm_clear_poison cleared the user-visible badblocks, and sent commands to the NVDIMM to clear the areas marked as 'poison', but it neglected to clear the same areas from the internal poison_list which is used to marshal ARS results before sorting them by namespace. As a result, once on-demand ARS functionality was added: 37b137f nfit, libnvdimm: allow an ARS scrub to be triggered on demand A scrub triggered from either sysfs or an MCE was found to be adding stale entries that had been cleared from gendisk->badblocks, but were still present in nvdimm_bus->poison_list. Additionally, the stale entries could be triggered into producing stale disk->badblocks by simply disabling and re-enabling the namespace or region. This adds the missing step of clearing poison_list entries when clearing poison, so that it is always in sync with badblocks.
