Vincent Palatin 5d8e326da3 stm32l: avoid spurious USART interrupts ...

The TX empty interrupt needs an actual write to DR to be cleared.
So, we de-activate it before filling the TX buffer to ensure the
interrupt won't fire after the last write.

BUG=None
TEST=run EC console along with a lower priority task on Discovery board,
and check the task is scheduled as expected.
