Nipick: I usually find it easier to read if we break around conditions
instead of inside them:
if (scsi_prot_sg_count(cmd) &&
cmd->prot_sdb->table.sgl != scsi_prot_inline_sg(cmd))

Hmm. Maybe we just need to pass an nr_inline_vecs argument
to sg_alloc_table_chained to replace the SG_CHUNK_SIZE argument instead
of open coding this logic?
If we'd also pass it to sg_free_table_chained we could also simplify
those checks in all callers.
