Subject: iio: gyro: bmg160: fix buffer read values

From: Irina Tirdea <irina.tirdea@intel.com>

commit b475c59b113db1e66eb9527ffdec3c5241c847e5 upstream.

When reading gyroscope axes using iio buffers, the values
returned are always 0. In the interrupt handler, the return
value of the read operation is returned to the user instead
of the value read. Return the value read to the user.

This is also fixed in commit 82d8e5da1a33 ("iio:
accel: bmg160: optimize transfers in trigger handler").
