When flying as a fixed wing aircraft, a misaligned magnetometer can cause an error in pitch/roll and accel bias estimates.
When MAG_FUSE_TYPE_AUTOFW is selected and the vehicle is flying as a fixed wing as detected by the use of wind estimation
and current airspeed estimates, then magnetometer fusion is only allowed to access the magnetic field states.
