azurerm_iothub - fix a bug for local_auth_enabled

[ziyeqf]

GET on the resource might be returned with 404 just after an update. tracked on Azure/azure-rest-api-specs#27183

which might cause the following error:

 Error: Provider produced inconsistent result after apply
        When applying changes to azurerm_iothub.test, provider
        "provider[\"registry.terraform.io/hashicorp/azurerm\"]" produced an
        unexpected new value: Root resource was present, but now absent.
        This is a bug in the provider, which should be reported in the provider's own
        issue tracker.
