    nfs_clrpcops.c: Change initial layout type to flex files
    
    Since the File 4.1 layout is only supported by some
    large configurations of Netapp Filers, switch the client
    pNFS code to attempting to use Flexible File Format first.
    
    File 4.1 Layout should still work for any servers that do
    no support Flexible File Layout.
