stepcompress: Pass clock to stepcompress_set_last_position() 

Using sc->last_step_clock for the last position marker does not work
properly, because the stepper.py code calls stepcompress_reset() prior
to calling stepcompress_set_last_position().  Fix by passing an
explicit clock to stepcompress_set_last_position().
