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.
