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.
Addresses-Coverity-ID: 1446733 ("Unchecked return value")
Fixes: b5969abfa8b8 ("iio: imu: st_lsm6dsx: add motion events")
Fixes: 290a6ce11d93 ("iio: imu: add support to lsm6dsx driver")
