  Fix a bug in anonymous address space area sharing. Call the backend's share
  function only if the source area is not already shared. Otherwise increment the
  sh_info refcount. Without this fix, the kernel will try to recreate the pagemap
  if three and more address space areas attempt to share the same data.
