This fixes an abort when
CONFIG proxy.config.http.cache.open_write_fail_action INT 5is set which rewinds the state machine to before cache read/write.
This was tested by simulating a manifest that updates every 10s with max-age=1 cache control, hitting that asset with a thundering herd.
The failure was happening with a cache hit on a stale manifest.
While this "fix" allows ATS to to run without aborting, under testing 1 or more transactions end up with a client timeout with no bytes transferred.
