fix template for create custom implementation scenario

[kumargauravsharma]

Issue #, if available:
Code generator fails when custom implementation is provided for create scenario
Steps to reproduce:

1. Run make build-ack-generate && make build-controller SERVICE=$SERVICE
2. Observe:

   /Users/kumargsh/ws/github_ws/go/src/github.com/aws-controllers-k8s/elasticache-controller/pkg/resource/snapshot/sdk.go:311:17: expected ';', found created
   Error: not all generators ran successfully

3. Corresponding sdk.go code:

   exit := rlog.Trace("rm.sdkCreate")
   defer exit(err)created, err = rm.CustomCreateSnapshot(ctx, desired)
   if created != nil || err != nil {
   return created, err
   }

Observe, missing newline after defer exit(err)

Description of changes:
Updated the template.

Testing

• make test passed.
• ElastiCache service controller gets generated fine.
