When retrieving the enum value associated with typed data during "is data zero?" checking in btf_dump_type_data_check_zero(), the return value of btf_dump_get_enum_value() is not passed to the caller if the function returns a non-zero (error) value. Currently, 0 is returned if the function returns an error. We should instead propagate the error to the caller.
