Description of your changes

Fix conflicts, when instance creates with network interface reference. Example:

apiVersion: ec2.aws.jet.crossplane.io/v1alpha2
kind: Instance
metadata:
  name: instance-a
spec:
  forProvider:
    region: us-east-2
    ami: ami-0b332808c98813fef
    instanceType: c5.xlarge
    keyName: key
    networkInterface:
    - deviceIndex: 0
      networkInterfaceIdRef:
        name: ni-a
  deletionPolicy: Delete
  providerConfigRef:
    name: default

I am not quite sure, that this is good idea to just ignore this fields, but it seems like there is no other solution right now.

I have:

• [x] Read and followed Crossplane's contribution process.
• [x] Run make reviewable test to ensure this PR is ready for review.

How has this code been tested
