migration: avoid using error_is_set and thus relying on errp != NULL

The migration code is using errp to detect "internal" errors, this means
that it relies on errp being non-NULL.

No impact so far because our only QMP clients (the QMP marshaller and HMP)
never pass a NULL Error **.  But if we had others, this patch would make
sure that migration can work with a NULL Error **.
