iio: Un-inline iio_buffer_enabled()
As we are going to hide the currentmode inside the opaque structure,
this helper would soon need to call a non-inline function which would
simply drop the benefit of having the helper defined inline in a header.
One alternative is to move this helper in the core as there is no more
interest in defining it inline in a header. We will pay the minor cost
either way.
Let's do like the iio_device_id() helper which also refers to the opaque
structure and gets defined in the core.
