Fix conditional jump on uninitialized value
Fix conditional jump on uninitialized value

The inform_integration_evidence function defers some error checks
to inform_integration_evidence_parts, but failed to check
the errors before performing some logic. This was resulting in
a few conditional jumps on values that were supposed to be
initialized in the parts function.

This has been resolved.
