From: Andy Adamson <andros@xxxxxxxxxx>
When a clientid is stale, the sequence operation will return NFS4ERR_BADSESSION
or NFS4ERR_DEADSESSION. This will put the session into reset mode, and
run the session_reclaimer thread which calls destroy_session and
create_session. Destroy_session will also return NFS4ERR_BADSESSION or
NFS4ERR_DEADSESSION which is ignored by the session reset. Create_session
will return NFS4ERR_STALE_CLIENTID and the session reclaimer sets the
nfs_client cl_state to NFS4CLNT_LEASE_EXPIRED.
Catch the NFS4CLNT_LEASE_EXPIRED cl_state in nfs4_find_slot, and attempt to
recover the expired client id.
