fraud_detection: Improve accuracy for 'concurrent calls'
Avoid using the DLGCB_FAILED callback, since it has no protection
against the "408 Request Timeout / 200 OK" race condition, and simply
use DLGCB_DESTROY in order to decrement the concurrent calls counter.
This fixes a bug where a "408 Timeout / 200 OK" call would cause a
concurrent calls value of 4294967295, due to an extra decrement.
Fixes #2079
(cherry picked from commit 2404b96c87982387071cea63f5fc42d9169d8798)
