NFSv4: Don't call nfs4_reclaim_complete() on receiving NFS4ERR_STALE_CLIENTID

NFSv4: Don't call nfs4_reclaim_complete() on receiving NFS4ERR_STALE_CLIENTID

commit 6eaa61496fb3b93cceface7a296415fc4c030bce upstream.

If the server sends us an NFS4ERR_STALE_CLIENTID while the state management
thread is busy reclaiming state, we do want to treat all state that wasn't
reclaimed before the STALE_CLIENTID as if a network partition occurred (see
the edge conditions described in RFC3530 and RFC5661).
What we do not want to do is to send an nfs4_reclaim_complete(), since we
haven't yet even started reclaiming state after the server rebooted.
