When it fails to allocate fragment, it does not free and return error. And check the pointer inappropriately.

Thanks! As Maíra points out, the added kunit_kfree() call isn't strictly necessary, though it definitely doesn't hurt (and it's probably a nice thing to free memory early if we're already in a pretty dire memory situation). So I think it's an improvement.
The IS_ERR check is definitely a fix, though.
