When rs485 transmission over an 8250 port stops, __stop_tx() assigns active_timer = NULL before calling __stop_tx_rs485(). That function in turn either assigns active_timer = stop_tx_timer and rearms the timer (in case a delay_rts_after_send needs to be observed) or directly calls __do_stop_tx_rs485(). Move the assignment active_timer = NULL to __stop_tx_rs485() into the branch which directly calls __do_stop_tx_rs485(), thereby avoiding a duplicate assignment and simplifying the code.
