util/amdfwtool: Clarify APOB NV requirements

Relocate the first size check.  This was automatically continuing
and not looking for the caller incorrectly passing a destination.

New information indicates that the APOB_NV should always be present
in the system.  Augment the missing size check to inferring whether
a missing size is valid, as in the case of older products, or truly
missing when it's needed.
