drm/i915: Restore current RPS state after reset
Following commit 821ed7df ("drm/i915: Update reset path to fix incomplete requests") we no longer mark the context as lost on reset as we keep the requests (and contexts) alive. However, RPS remains reset and we need to restore the current state to match the in-flight requests.
