qemu: blockjob: Finish handling job with broken data

Now that we have a separate job type which will not trigger normal code
paths for terminating job we can remove the ad-hoc handling.

This possibly fixes the issue of a broken job inheriting the disk and
then finishing in which case we'd not detach the backing chain.
