libcamera: converter: Check converter validity
The ConverterFactoryBase::create() function returns a nullptr when no converter is found. The only caller, SimpleCameraData::init(), checks if the converter is valid with isValid(), but doesn't check if the pointer is null, which can lead to a crash. We could check both pointer validity and converter validity in the caller, but to limit the complexity in callers, it is better to check the converter validity in the create() function and return a null pointer when no valid converter is found.
