Mi Jinlong 0de1b7e800 nfs: kernel should return EPROTONOSUPPORT when not support NFSv4 
When nfs client(kernel) don't support NFSv4, maybe user build
  kernel without NFSv4, there is a problem.

  Using command "mount SERVER-IP:/nfsv3 /mnt/" to mount NFSv3
  filesystem, mount should should success, but fail and get error:

    "mount.nfs: an incorrect mount option was specified"

  System call mount "nfs"(not "nfs4") with "vers=4",
  if CONFIG_NFS_V4 is not defined, the "vers=4" will be parsed
  as invalid argument and kernel return EINVAL to nfs-utils.

  About that, we really want get EPROTONOSUPPORT rather than
  EINVAL. This path make sure kernel parses argument success,
  and return EPROTONOSUPPORT at nfs_validate_mount_data().
