[Bug] When the sensor is disabled via boardconfig, the code throws an error during the build process.

Describe the bug

The environment where I use the vehicle is not suitable for the magnetometer, so in older versions of the PX4 Autopilot software, I disabled the magnetometer on the vehicle using the 'make px4_fmu-v6c_default boardconfig' command followed by 'modules->ekf2->mag disable'. However, after updating to the latest version of the PX4 Autopilot software, I encountered errors when performing the same procedure.

error:

/ekf2/EKF2.cpp:2838:28: error: 'vehicle_magnetometer_s' was not declared in this scope; did you mean 'vehicle_odometry_s'?
 2838 |     uORB::SubscriptionData<vehicle_magnetometer_s> vehicle_mag_sub{ORB_ID(vehicle_magnetometer), mag};
      |                            ^~~~~~~~~~~~~~~~~~~~~~
      |                            vehicle_odometry_s
compilation terminated due to -Wfatal-errors.

To Reproduce

1. I connected the drone to the computer using a USB cable.
2. I ran the 'make px4_fmu-v6c_default boardconfig' command in the directory where the PX4 Autopilot software is located.
3. I disabled the 'modules->ekf2->mag' section.
4. I attempted to upload to the vehicle using the 'make px4_fmu-v6c_default upload' command.

Expected behavior

In older versions, at the beginning of 1.14 and 1.15, it was building and uploading to the vehicle without any issues, and the vehicle would detect its initial position as 0 every time it was restarted
