Alexey Marchuk 42f59f5006 lib/reduce: Copy user's buffers if SGL is not supported
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.
