Bug 21181: Make cancel_expired_reserves.pl Cancel all holds not waiting if ExpireReservesMaxPickupDelay not set

To test:
0 - Make sure ExpireReservesMaxPickupDelay is set to 'Don't allow'
1 - Place a hold for a patron
2 - Check in at another library to set it in transit
3 - Update expirationdate of hold to be in the past
    UPDATE reserves SET expirationdate='1999-12-31'
4 - Run cancel_expired_holds.pl
5 - Hold is not canceled
6 - Apply patch
7 - Run again
8 - Hold is cancelled
