  Set initial values for nfsstatfs in the NFSv4 client.
  
  The AmazonEFS NFSv4.1 server does not support the FILES_FREE and FILES_TOTAL
  attributes. As such, an NFSv4.1 mount to the server would return garbage
  for these values. This patch initializes the fields of the nfsstatfs structure,
  so that "df" and friends will at least return consistent bogus values.
