Using zio_data_buf_alloc() to allocate the itx's may be unsafe because the itx->itx_lr.lrc_reclen field is not constant from allocation to free. Using a different itx->itx_lr.lrc_reclen size in zio_data_buf_free() can result in the allocation being returned to the wrong kmem cache. This issue can be avoided entirely by storing the allocation size in itx->itx_size and using that for zio_data_buf_free().
