nfs_clrpcops.c: Change initial layout type to flex files

Browse Source 
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.
