Bug 13735: Update PrepareItemrecordDisplay to use maxlength

The PrepareItemrecordDisplay method used to generate the item
display on receiving serials was using a hardcoded maxlength
of 255 on input fields. This patch updates it to use the
maxlength defined in the frameworks instead as the normal
item form does.

To test:
- Create or reuse an existing subscription
- Make note of the framework the record uses
- Add an item on receive
- Check the maxlength on the various fields is set to 255
  (check source code or use developer tools)
- You can also verify that by adding a long note to
  one of the note fields
- Apply patch
- Repeat tests, the maxlength should now be 9999
- In your framework settings, change the length of one
  of the subfields to another value
- Verify that the item form reflects the change
