Bug 29007: Add cancellation reason input on check in

Test plan:

1) Check an item in with already a confirmed hold
2) Cancel the hold, it was cancelled without possibility to choosing a
   reason
3) Apply this patch and do it again, you must see an input to choose
   your cancellation reason (list from VA)
