iio: imu: kmx61: fix information leak in triggered buffer
commit 6ae053113f6a226a2303caa4936a4c37f3bfff7b upstream.
The 'buffer' local array is used to push data to user space from a
triggered buffer, but it does not set values for inactive channels, as
it only uses iio_for_each_active_channel() to assign new values.
Initialize the array to zero before using it to avoid pushing
uninitialized information to userspace.
