The dmi-sysfs should create "End of Table" entry, that is type 127. But after adding initial SMBIOS v3 support fc43026278b2 (dmi: add support for SMBIOS 3.0 64-bit entry point) the 127-0 entry is not handled any more, as result it's not created in dmi sysfs for instance. This is important because the size of whole DMI table must correspond to sum of all DMI entry sizes.
So move the end-of-table check after it's handled by dmi_table.
