tdclib: fread calls read to get one item per time.

Read can potentially gead more than 1 element per call, despite with the current zio design thast won't happen. But in any case, fread must call read to get one item per time, and not n-i, so if the zio behaviour changes and read can get more than one element, no date gets lost.
