ftdi: flush mpsse queue after a level change on reset pins
The function ftdi_set_signal() does not propagate the pin change until next call to mpsse_flush(). Current code does not toggles immediately the reset pins if polling is turned off. Call mpsse_flush() at the end of ftdi_reset(). While there, remove the duplicated LOG message.
