provide gpuid in PolicyViolation

[ilyee]

I am using go-dcgm to receive policy violation events, but I find PolicyViolation struct does not contain gpu index

// PolicyViolation represents a detected violation of a policy condition
type PolicyViolation struct {
	// Condition specifies the type of policy that was violated
	Condition policyCondition
	// Timestamp indicates when the violation occurred
	Timestamp time.Time
	// Data contains violation-specific details
	Data any
}

But in dcgmPolicyCallbackResponse_v2 struct from which we generates the PolicyViolation we can see there is a gpuId

/**
 * Define the structure that is given to the callback function
 */
typedef struct
{
    // version must always be first
    unsigned int version; //!< version number (dcgmPolicyCallbackResponse_version)

    dcgmPolicyCondition_t condition; //!< Condition that was violated
    union
    {
        dcgmPolicyConditionDbe_t dbe;         //!< ECC DBE return structure
        dcgmPolicyConditionPci_t pci;         //!< PCI replay error return structure
        dcgmPolicyConditionMpr_t mpr;         //!< Max retired pages limit return structure
        dcgmPolicyConditionThermal_t thermal; //!< Thermal policy violations return structure
        dcgmPolicyConditionPower_t power;     //!< Power policy violations return structure
        dcgmPolicyConditionNvlink_t nvlink;   //!< Nvlink policy violations return structure
        dcgmPolicyConditionXID_t xid;         //!< XID policy violations return structure
    } val;

    unsigned int gpuId; //!< GPU ID of GPU which violated the policy.
} dcgmPolicyCallbackResponse_v2;

So i wonder can we add gpu index into PolicyViolation so we can see which gpu the violation belongs to? We can just add a simple gpuID = uint(response.gpuId) in the following code:

go-dcgm/pkg/dcgm/policy.go

Lines 202 to 207 in 7c92211

	func ViolationRegistration(data unsafe.Pointer) int {
	var con policyCondition
	var timestamp time.Time
	var val any
	response := *(*C.dcgmPolicyCallbackResponse_t)(data)
