Subject: [PATCH] iio: adc: ad7173: check return value of spi_setup()

Check the return value of spi_setup() and propagate the error in the
ad7173_probe() function. This is unlikely to happen since virtually
every SPI controller supports SPI_MODE_3, but still always a good idea
to check the return value.
