iio: imu: st_lsm6dsx: check return value from st_lsm6dsx_sensor_set_enable

Add missing return value check in st_lsm6dsx_read_oneshot disabling the
sensor. The issue is reported by coverity with the following error:

Unchecked return value:
If the function returns an error value, the error value may be mistaken
for a normal value.
