* modules/md/md_util.c (md_text_fcreatex): Return the status of the
  write and the close.  The permissions were set a second time here,
  overwriting the status; md_util_fcreatex() already sets them.
  (md_util_freplace): Keep the status of the last file creation, so a
  failure to create the temporary file can no longer be reported as
  success and have the write use an uninitialized handle.  Remove the
  temporary file when the write fails too, not only on rename failure.
