   In the case of a recovery read, we rely on a NoSuchEntry response on the
   first missing entry to determine the final LAC.  As such, we need to
   consider an entry to be gone once we see wQ-aQ+1 NoSuchEntry/Ledger
   responses from bookies.  Otherwise, a zombie bookie can prevent ledger
   recovery from suceeding indefinitely (it'll hit the timeout each time).
