wifi: ath12k: refactor per-radio thermal hwmon setup and cleanup

Both the error path in thermal registration and the normal thermal unregister
path performed the same hwmon device unregistration and pointer cleanup.
Consolidate this logic into a single helper to reduce code duplication and ensure
consistent cleanup across all paths. Add a helper to set up the hwmon registration
during thermal registration to keep symmetry with thermal cleanup.
