### Problem Description

The geoip ingest processor adds a `_geoip_database_unavailable_*` tag field to documents when the database cannot be downloaded, even if the source field does not exist and `ignore_missing` is set.

### Steps to Reproduce

1. Run Elasticsearch with `ingest.geoip.downloader.enabled=false`
2. Execute the following request in the console:

```
POST /_ingest/pipeline/_simulate
{
  "pipeline": {
    "processors": [
      {
        "geoip": {
          "field": "client.ip",
          "target_field": "client.geo",
          "ignore_missing": true
        }
      }
    ]
  },
  "docs": [
    {
      "_index": "index",
      "_source": {}
    },
    {
      "_index": "index",
      "_source": {"client": {"ip": "8.8.8.8"}}
    }
  ]
}
```

This produces:

```
{
  "docs" : [
    {
      "doc" : {
        "_index" : "index",
        "_id" : "_id",
        "_source" : {
          "tags" : [
            "_geoip_database_unavailable_GeoLite2-City.mmdb"
          ]
        },
        "_ingest" : {
          "timestamp" : "2022-06-03T02:33:16.49692803Z"
        }
      }
    },
    {
      "doc" : {
        "_index" : "index",
        "_id" : "_id",
        "_source" : {
          "client" : {
            "ip" : "8.8.8.8"
          },
          "tags" : [
            "_geoip_database_unavailable_GeoLite2-City.mmdb"
          ]
        },
        "_ingest" : {
          "timestamp" : "2022-06-03T02:33:16.496934873Z"
        }
      }
    }
  ]
}
```

I would expect only the second document to have the tag added.
