NFSv4: Prevent NULL-pointer dereference in nfs42_complete_copies()

On the node of an NFS client, some files saved in the mountpoint of the NFS server were copied to another location of the same NFS server. Accidentally, the nfs42_complete_copies() got a NULL-pointer dereference crash with the following syslog:
