iio: adc: ti-ads1018: reject devices without match data
SPI driver_override allows a device to bind to this driver without
matching either the OF or SPI device ID table. In that case,
spi_get_device_match_data() returns NULL.
ads1018_spi_probe() immediately dereferences the returned chip
information to initialize the IIO device, causing a NULL pointer
dereference.
Commit 572a00852635 ("iio: dac: ad5686: missing NULL check on match
data") fixed the same driver_override issue in another SPI driver.
Reject devices without match data before allocating the IIO device.
Fixes: bf0bba486b5b ("iio: adc: Add ti-ads1018 driver")
