If the server returns with EAGAIN when we're trying to recover from a server reboot, we currently delay for 1 second, but then mark the stateid as needing recovery after the grace period has expired. Instead, we should just retry the same recovery process immediately after the 1 second delay. Break out of the loop after 10 retries.
