nfsd4: don't set cl_firststate on first reclaim in 4.1 case
We set cl_firststate when we first decide that a client will be permitted to reclaim state on next boot. This happens: - for new 4.0 clients, when they confirm their first open - for returning 4.0 clients, when they reclaim their first open - for 4.1+ clients, when they perform reclaim_complete We also use cl_firststate to decide whether a reclaim_complete has already been performed, in the 4.1+ case. We were setting it on 4.1 open reclaims, which caused spurious COMPLETE_ALREADY errors on RECLAIM_COMPLETE from an nfs4.1 client with anything to reclaim.
