hierarchical device role does not report device count correctly

[chris240189]

Deployment Type

Self-hosted

NetBox Version

v4.3.4

Python Version

3.12

Steps to Reproduce

1. Create a number of device roles and assign devices to them
2. Create a new device role to be used as parent
3. Assign the role from step 2 as parent to the roles from step 1
4. Check the list of device roles and the number of devices

I was also able to replicate this on demo.netbox.dev

Expected Behavior

The parent device role should show and count all direct and hierarchical assigned devices.

Observed Behavior

The device role device count only considers directly assigned devices.
