Revert "NFSD: Force all NFSv4.2 COPY requests to be synchronous"
In the past several kernel releases, we've made NFSv4.2 async copy
reliable:
- The Linux NFS client and server now both implement and use the
NFSv4.2 OFFLOAD_STATUS operation
- The Linux NFS server keeps copy stateids around longer
- The Linux NFS client and server now both implement referring call
lists
And resilient against DoS:
- The Linux NFS server limits the number of concurrent async copy
operations
