    nfscl: Enable support for the Lookup+Open RPC
    
    Commits 3ad1e1c1ce20 and 57014f21e754 added a Lookup+Open
    RPC for NFSv4.1/4.2, which can reduce the RPC count by
    10-20% for some loads.  This has now received a fair amount
    of testing, so I think it is ok to enable it.
    
    Note that the Lookup+Open RPC is only used when the
    "oneopenown" mount option is specified.  As such, this
    change won't affect most NFSv4.1/4.2 mounts.
