iio: adc: ad9361: Fix ad9361_set_trx_clock_chain()

ad9361_dig_tune() shouldn't be called if conv is not available. This situation occurs when ad9361_setup() is called by ad9361_probe() (axi_converver is not yet registered using ad9361_register_axi_converter). Signed-off-by: Dragos Bogdan <[email protected]>
