iio: frequency: adf4377: 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 the result is later dereferenced by the property parsing and
initialization paths.

Reject devices without match data before continuing probe.
