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.
