Disable the UDRE interrupt sooner in HardwareSerial
Before, the interrupt was disabled when it was triggered and it turned out there was no data to send. However, the interrupt can be disabled already when the last byte is written to the UART, since write() will always re-enable the interrupt when it adds new data to the buffer. Closes: #1008
