Remove useless call to stm32_usart_serial_en_wakeup() routine in suspend callback. When called with "false" argument, this routine is clearing UESM and WUFIE bits if usart is not wakeup source. Those bits are already cleared in set_termios(), and then in serial_resume() callback when usart is wakeup source.
