iio: dummy: iio_simply_dummy_buffer: fix information leak in triggered buffer
The 'data' array is allocated via kmalloc() and it 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.
Use kzalloc for the memory allocation to avoid pushing uninitialized
information to userspace.
