When master-retry-count equals 0, it means the slave will
try to reconnect to the master continuously. But, when the number
of tries err_count overflows to 0, the connection will abort.
So, when an overflow occurs, we still need to check master-retry-cout
value. If master-retry-count equals 0, reconnection should continue.
