as a normal consequence of subtree migration. From Zheng:
"handle_client_caps on unknown ino xxx” is normal after migrating a subtree
Sequence of events that cause this are:
- client sends caps message to mds.a
- mds finishes subtree migration, send cap export to client
- mds trim its cache
- mds receives cap messages from client
Raise debugging of this message so it doesn't flood the log.
