acpi/nfit: Issue Start ARS to retrieve existing records
ACPI 6.2 defines in section 9.20.7.2 that the OSPM may call a Start ARS with Flags Bit [1] set upon receiving the 0x81 notification. Upon receiving the notification, the OSPM may decide to issue a Start ARS with Flags Bit [1] set to prepare for the retrieval of existing records and issue the Query ARS Status function to retrieve the records. Add support to call a Start ARS from acpi_nfit_uc_error_notify() with ND_ARS_RETURN_PREV_DATA set when HW_ERROR_SCRUB_ON is not set.
