media: atmel: atmel-isc: make try_fmt error less verbose

Browse Source 
In case the sensor refuses to set the format, avoid printing the error
message that no compatible format was found.
This means that the try_fmt will be less verbose.
The error will be printed only if really a format cannot be found.
Some application try all possible formats in a row (gstreamer e.g.)
which will flood the console with error messages until a working one is found.
