OvmfPkg/VirtNorFlashDxe: sanity-check variables

Browse Source 
Extend the ValidateFvHeader function, additionally to the header checks
walk over the list of variables and sanity check them.

In case we find inconsistencies indicating variable store corruption
return EFI_NOT_FOUND so the variable store will be re-initialized.
