iio: amplifiers: ad8366: reject devices without match data

Browse Source 
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 ad8366_probe() later dereferences the result while setting up the
IIO device.

Reject devices without match data before using the chip information.
