Invalid entry length (0). DMI table is broken! Stop.

I am trying to run redhat-certification tests on some ARM Edge systems including NXP I.MX8 and Nvidia systems

Please see https://issues.redhat.com/browse/CERTPX-11489 for details

We use dmidecode to plan the proper tests and it is also a subtest to determine supportability.

On NXP I.MX8 I am seeing this for dmidecode

It has been suggested in the above Jira that dmidecode should not crash on a single broken table.  It has also been suggested that this is a firmware issue and the hardware partner has to fix their bad firmware tables so that the tables are valid and not change dmidecode

I am filing this Jira to keep track of the issue and the fix if one is deemed necessary
