iio: dac: mcp4821: reject devices without match data
A device bound through driver_override need not match an entry in the
driver tables. In that case spi_get_device_match_data() returns NULL,
but mcp4821_probe() dereferences the result while configuring the IIO
device.
Reject devices without match data before using the chip information.
