"LensPosition" property could not be read properly

[hunkus]

If the property is read through this after auto focus or manual focus adjustment,
the following is always displayed.

1. Auto-focus

picam2.set_controls({"AfMode": 1 ,"AfTrigger": 0})
pos_vals = picam2.camera_controls["LensPosition"]
print(pos_vals)

(0.0, 1000.0, 100.0)

2. Manual-focus

picam2.set_controls({"AfMode": 0, "LensPosition": 0.0})
pos_vals = picam2.camera_controls["LensPosition"]
print(pos_vals)

(0.0, 1000.0, 100.0)
