Fix inability to suspend holds

Fix inability to suspend holds

The hold status code was being used for "has the hold been captured", but
the value for "frozen" was after the cutoff being assumed for "captured".

So check for the suspended code specifically in the if, and don't return
the suspended code if there is a capture time.
