ACPI, APEI, Fix APEI related table size checking
On Huang Ying's machine:
erst_tab->header_length == sizeof(struct acpi_table_einj)
but Yinghai reported that on his machine,
erst_tab->header_length == sizeof(struct acpi_table_einj) -
sizeof(struct acpi_table_header)
To make erst table size checking code works on all systems, both
testing are treated as PASS.
Same situation applies to einj_tab->header_length, so corresponding
table size checking is changed in similar way too.
v2:
- Treat both table size as valid
