iio: accel: adxl313: 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.
adxl313_spi_probe() dereferences chip_data to select the regmap
configuration, 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 selecting the configuration.
Fixes: d6e3ee74d16f ("iio: accel: adxl313: simplify with spi_get_device_match_data()")
