[OE-core] [PATCH] smartpm: Don't ignore error if RPM transaction fails without problems

Hello,

Hmm, it sounds like the attempt mode wants to ignore installation failures
(empty problems list) like before the patch, which makes sense to me. Afterall,
attempt mode wants to try installation and ignore failures. So it seems good to
fix this regression too.

However, I wonder why it never ignored a non-empty problems list, which would
also trigger an error. Maybe that case just never happens in practice, because
it's always just file conflicts. Those trigger a retry, which prevents the error
from being raised.

Indeed, I'm curious about that too...

If you could put together the patch, that would be great and fine with me.

Thanks,
Daniel
