drm/xe/guc: Fix uninitialised count in GuC load debug prints

Browse source

The debug prints about how long the GuC load takes have a loop
counter. However that was neither initialised nor incremented! Plus,
counting loops is no longer meaningful given the wait function returns
early for any change in the status value. So fix it to only count
loops due to actual timeouts.
