RFR: 8310874: Runthese30m crashes with klass should be in the placeholders during verification [v2]

[Coleen Phillimore]

> For non-parallel capable class loaders, the class is not put in the placeholders table, so a verification at the wrong time will hit this assert.  This trivial change removes the invalid assert.
> Tested with inserting a LoaderConstraintTable::verify while running jck tests.
