fixes following build error in intel-compute-runtime-native on Ubuntu 24.04 host:
error: ‘*(const NEO::ArgDescValue::Element*)((char*)&<unnamed> + offsetof(NEO::ArgDescValue, NEO::ArgDescValue::elements.StackVec<NEO::ArgDescValue::Element, 1, unsigned char>::onStackMemRawBytes[0]))’ may be used uninitialized [-Werror=maybe-uninitialized]
