bresch 61036599db mag_cal: fix mag bias estimate to mag cal
- since last_us is set to 0 every time the bias is not observable, the
  total time was also reset -> needed 30 consecutive seconds in mag 3D
  to be declared "stable"
- after landing, the mag_aligned_in_flight flag is reset. Using this for
  bias validity makes it invalid before we have a chance to save it to
  the calibration.
