In the compression operation we may have SGL input if user's buffer is fragmented or less than chunk_size. If the backing device doesn't support SGL input then we should copy user's buffers into decomp_buffer (including paddings if any). In the decompression operation, if the backing device doesn't support SGL output, we use a single output buffer which is pointing to decomp_buffer. Once the operation completes, we should copy the result into user's buffers.
