Zach BrownandZach Brown 07c9edb58f scoutfs: warn on compaction stale seg reads ...

It's possible to trigger stale segment reads during compaction.  This
shouldn't be possible during regular operation because the server
protects the input segments while the compaction is pending.  Stale
segment reads can only happen to client reads which aren't serialized
with segment allocation and writes.

Warn if we see a stale segment read during compaction.  It means that we
either have a bug in the server or someone armed a stale segment read
trigger that hit compaction.
