iio: core: remove extra semi-colon from devm_iio_device_register() macro

commit a0747914 upstream.

This change removes the semi-colon from the devm_iio_device_register()
macro which seems to have been added by accident.

Fixes: 63b19547 ("iio: Use macro magic to avoid manual assign of driver_module")
