Log:
  Return the correct error for Seek at EOF.
  
  The Linux NFSv4.2 client expects an NFSERR_NXIO error to be returned
  when a NFS4_CONTENT_DATA request with sa_offset == file_size is done for Seek.
  (This is not actually what RFC-7862 says is the correct reply for this
  operation request, so it is only done when vfs.nfsd.linux42server is set.)
  Anyhow, without this patch the code erroeously returned NFSERR_INVAL.
