[Bug]: [GoSDK] After loading partial fields successfully, searching and output "*" fields reports an error

[ThreadDao]

Is there an existing issue for this?

• I have searched the existing issues

Environment

- Milvus version: master-20241118-12ed40e1-amd64
- Deployment mode(standalone or cluster):
- MQ type(rocksmq, pulsar or kafka):    
- SDK version(e.g. pymilvus v2.0.0rc2): go sdk
- OS(Ubuntu or CentOS): 
- CPU/Memory: 
- GPU: 
- Others:

Current Behavior

1. collection has many fields
2. load partial fields:

	partialLoadedFields := []string{common.DefaultInt64FieldName, common.DefaultVarcharFieldName, common.DefaultFloatVecFieldName, common.DefaultFloat16VecFieldName}

3. search and output "*", sdk parser output fields failed:

"extra output fields [int32Array int8Array int16Array int64Array floatArray doubleArray int8 int16 binaryVec varcharArray bf16Vec bool int32 boolArray json float double] found and result does not dynamic field"]

• case:

func TestLoadPartialFields(t *testing.T) {
	/*
		1.  verify the collection loaded successfully
		2.  verify the loaded fields can be searched in expr and output_fields
		3.  verify the skip fields not loaded, and cannot search/query/hybrid search with them in expr or output_fields
