With Dave's recent fix [1], we can restore error clearing for btt i/o in
4.12.
ACPI 6.1 introduced new health state flags. Beyond reflecting them in
the dimmX/flags sysfs attribute we also need to handle the deeper
implications of the ACPI_NFIT_MEM_MAP_FAILED flag which changes
assumptions on how the driver discovers dimms. In the "map failed" case
there may missing or no SPA entries associated with a dimm. Those dimms
should still be registered with libnvdimm so that the error state can be
communicated and recovery attempted.
