iio: bmi160_core: Fix sparse warning due to incorrect type in assignment

There is a type mismatch between the buffer which is of type s16 and the
samples stored, which are declared as __le16.

Fix the following sparse warning:
drivers/iio/imu/bmi160/bmi160_core.c:411:26: warning: incorrect type
in assignment (different base types)

drivers/iio/imu/bmi160/bmi160_core.c:411:26: expected signed short
[signed] [short] [explicitly-signed] <noident>
drivers/iio/imu/bmi160/bmi160_core.c:411:26: got restricted __le16
[addressable] [usertype] sample

This is a cosmetic-type patch since it does not alter code behaviour.
The le16 is going into a 16bit buf element, and is labelled as IIO_LE in the
channel buffer definition.
