Tony Luck fc8c6b8bb2 ACPI: extlog: Handle multiple records ...

[ Upstream commit f6ec01da40e4139b41179f046044ee7c4f6370dc ]

If there is no user space consumer of extlog_mem trace records, then
Linux properly handles multiple error records in an ELOG block

	extlog_print()
	  print_extlog_rcd()
	    __print_extlog_rcd()
	      cper_estatus_print()
		apei_estatus_for_each_section()

But the other code path hard codes looking for a single record to
output a trace record.

Fix by using the same apei_estatus_for_each_section() iterator
to step over all records.
