linux-gen: crypto: set packet error flag depending on crypto result operation

To speed up fast path of crypto packet operations, set error flag depending on the crypto result operation. This allows applications to fast-forward packets w/o errors and inspect crypto result only for erroneous packets.

linux-gen: crypto: drop extra memcpy on result return

There is no need to fill local struct and then copy it to packet. Just fill packet data directly, saving one memcpy call.
