Splits producing more than one ubatch per batch for recurrent models were broken with #14512.
This could cause SEGFAULTS and possibly other problems when using any
ubatch
size smaller than a processed batch with a recurrent model (e.g. Mamba, Mamba-2, etc.)(I first noticed this when getting a SEGFAULT with Mamba after updating #14139 to a commit after #14512 was merged)
This fixes it by moving the completeness check after the ubatch split loop.
