NFSv4.1: Enable open-by-filehandle
Sometimes, we actually _want_ to do open-by-filehandle, for instance when recovering opens after a network partition, or when called from nfs4_file_open. Enable that functionality using a new capability NFS_CAP_ATOMIC_OPEN_V1, and which is only enabled for NFSv4.1 servers that support it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
