Christopher Pascoe 4ef0466578 Don't trip the WDT if interrupts are disabled during write() or flush(). ...

Prior to this change, if interrupts were disabled during a call to
HardwareSerial::write() when the circular buffer was full, or
HardwareSerial::flush() when the circular buffer was non-empty,
we would loop forever and trip a watchdog timeout.
