media: atmel: atmel-isc: fix asd memory allocation
The subsystem will free the asd memory on notifier cleanup, if the asd is added to the notifier. However the memory is freed using kfree. Thus, we cannot allocate the asd using devm_* This can lead to crashes and problems. To test this issue, just return an error at probe, but cleanup the notifier beforehand.
