CONTAP-677909: RESTAPI doesn't return pagination link when the request times out with 0 records

Issue

• Despite having records to return, RESTAPI calls intermittently returns with 0 records and no pagination link when hitting the return_timeout value:
  [root@rhel1 ~]# curl -ku admin -X GET "https://cluster1/api/storage/volumes?return_timeout=1&max_records=3&fields=uuid%2Cefficiency&svm.name=svm1&efficiency.state=disabled"
{
"records": [
],
"num_records": 0,
"_links": {
"self": {
"href": "/api/storage/volumes?return_timeout=1&max_records=3&fields=uuid%2Cefficiency&svm.name=svm1&efficiency.state=disabled"
}
}

  

• The same call later returns the correct information, including a pagination link:
  [root@rhel1 ~]# curl -ku admin -X GET "https://cluster1/api/storage/volumes?max_records=3&fields=uuid%2Cefficiency&svm.name=svm1&efficiency.state=disabled"

}
}
