Originally, dmu_req_copy modifies bv_len and bv_offset in bio_vec so that it can continue in subsequent passes. However, after the immutable biovec changes in Linux 3.14, this is not allowed. So instead, we just tell dmu_req_copy how many bytes are already copied and it will skip to the right spot accordingly.
