Maybe just have version of submit_bio_noacct that takes the split
argument, and make submit_bio_noacct a tiny wrapper around it?  That
should create less churns than this version I think.  In fact I suspect
we can actually bypass submit_bio_noacct entirely, all the checks and
accounting in it were already done when submitting the origin bio, so
the bio split helper could just call into submit_bio_noacct_nocheck 
directly.
