Review comment:
@chia7712 Is there a reason why we need this change? If so, can we add a
test? If there is no data to unwrap, we would just throw the exception in the
IOException catch block below anyway. Since we only get here when the other
side has closed its connection, which is typically a handshake failure, I am
not sure we need to optimize.
