[PATCH 7/10] random pt2: kill dead extract_state struct

[Matt Mackall]

Remove unused extract_timer_state struct. It was formerly used to
feedback zero-entropy timing samples while extracting entropy, but
that had a tendency to overwhelm the batch processing queue and
prevent storing real samples.
