    drm/i915: Restore current RPS state after reset

    Following commit 821ed7df6e2a ("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.
