[PATCH v2 25/44] qom: Use return values to check for error where that's simpler

[Markus Armbruster <armbru@redhat.com>]

When using the Error object to check for error, we need to receive it
into a local variable, then propagate() it to @errp.

Using the return value permits allows receiving it straight to @errp.
