Bug 16158: Move GetAuthorisedValues outside the loop

Bug 16158: Move GetAuthorisedValues outside the loop

In catalogue/detail.pl and catalogue/moredetail.pl, the
GetAuthorisedValues subroutine is called once per item. It's not needed,
only 1 call is enough.

Test plan:
Edit item and view a catalogue record.
The withdrawn, lost and damaged values should be correctly
displayed/saved.
