Subject: [PATCH 60/76] ACPI, APEI, Fix ERST header length check

From: Jiang Liu <liuj97@...il.com>

This fixes a trivial copy & paste error in ERST header length check.
It's just for future safety because sizeof(struct acpi_table_einj)
equals to sizeof(struct acpi_table_erst) with current ACPI5.0
specification. It applies to v3.3-rc6.
