Paolo Bonzini 22fb6eb571 qom: fix objects with improper parent type
Some objects accidentally inherit ObjectClass instead of Object.
They compile silently but may crash after downcasting.

In this patch, we introduce a coccinelle script to find broken
declarations and fix them manually with proper base type.
