The st_lsm6dsx_sensor_settings struct's fs_avl[] array is expected to
be of size 4. We can't define it to be of size 3 and try to access
the 4th element below.
Commit c8d4066c7246 ("iio: imu: st_lsm6dsx: remove invalid gain value
for LSM9DS1") which is a "cleanup" change, results in an Ooops here
so revert it.
