Dan Williams 94e0c5ab52 acpi, nfit: fix health event notification 
commit adf6895754 upstream.

Integration testing with a BIOS that generates injected health event
notifications fails to communicate those events to userspace. The nfit
driver neglects to link the ACPI DIMM device with the necessary driver
data so acpi_nvdimm_notify() fails this lookup:

        nfit_mem = dev_get_drvdata(dev);
        if (nfit_mem && nfit_mem->flags_attr)
                sysfs_notify_dirent(nfit_mem->flags_attr);

Add the necessary linkage when installing the notification handler and
clean it up when the nfit driver instance is torn down.
