Olga Kornievskaia 18fa56ca4c NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION 
[ Upstream commit c907e72f58ed979a24a9fdcadfbc447c51d5e509 ]

When the client received NFS4ERR_BADSESSION, it schedules recovery
and start the state manager thread which in turn freezes the
session table and does not allow for any new requests to use the
no-longer valid session. However, it is possible that before
the state manager thread runs, a new operation would use the
released slot that received BADSESSION and was therefore not
updated its sequence number. Such re-use of the slot can lead
the application errors.
