Description of problem:

When creating a host that uses image based provisioning, if one of the needed templates uses the macro "host_enc" it fails with following error:

2024-02-29T15:00:55 [E|app|1c4c3394] Failed to save: Render user data template for louie-lessen.example.com task failed with the following error: undefined method `content_view' for nil:NilClass

Version-Release number of selected component (if applicable):

Satellite 6.14

How reproducible:

Steps to Reproduce:
1. Create an image associated with a compute resource. Select the "user data" checkbox.

2. Associate the template "Kickstart default user data" to the operating system used by the image

3. Try creating a host using the image above

Actual results:

Error to render the user data template.

Expected results:

Template to render successfully

Additional info:
The block that breaks the template in this specific example is this:

<% if host_enc['parameters']['realm'] && @host.realm && (@host.realm.realm_type == 'FreeIPA' || @host.realm.realm_type == 'Red Hat Identity Management') -%>
<%= snippet 'freeipa_register' %>
<% end -%>

I ran tests and it happens anytime host_enc is called. Removing that reference from the template allow it to render, but that's not a solution (however, works fine as a workaround)
