Clone args.PusherTx when passing it to an error
Clone args.PusherTx when passing it to an error

This is similar to #2601 (= copy args.Txn when copying into
reply.Txn). We still get a race error between TxnCoordSender and
Multiraft (#2669), and one possibility is that args.PusherTx is reused
for retries while it is accessed in the reply flow. (I'm not totally
sure..)
