After commit 5837c80e870b ("bio-integrity: Fix bio_integrity_verify
segment start bug"), loading scsi_debug with data integrity enabled
(for example modprobe scsi_debug dif=1 dix=1) starts hitting BUG_ON()
at bio_integrity_verify():
BUG_ON(total > bio->bi_integrity->bip_iter.bi_size);
Because bip_iter.bi_size has already been set to zero at this point
as a result of consuming bip_iter.
I can resolve this issue by removing the BUG_ON(). But I would like
to ask whether we should preserve an alternative assert, or not
before submitting the patch that simply removing the line.
