TlsSession state holder 'state_' is loaded twice when we check for its modification in the TlsSession state machine code. std::atomic_compare_exchange_strong returns false when 'state_' is not equals to 'old_state' and in this case 'old_state' is changed for the current value of 'state_'. So reload it right after the returns is not efficient and may also have an unexpected corner case. This patch re-uses the value of 'old_state' for next processing.
