iio: adc: ad7280a: handle spi_setup() errors in probe()
The probe() function ignored the return value of spi_setup(), leaving SPI
configuration failures undetected. If spi_setup() fails, the driver should
stop initialization and propagate the error to the caller.
Add proper error handling: check the return value of spi_setup() and return
it on failure.
