    NFS: Allow text-based mounts via compat_sys_mount
    
    The compat_sys_mount() system call throws EINVAL for text-based NFSv4
    mounts.
    
    The text-based mount interface assumes that any mount option blob that
    doesn't set the version field to "1" is a C string (ie not a legacy
    mount request).  The compat_sys_mount() call treats blobs that don't
    set the version field to "1" as an error.  We just relax the check in
    compat_sys_mount() a bit to allow C strings to be passed down to the NFSv4
    client.
