[DO NOT MERGE] fingerprint: handle PerformanceStats NULL pointers

bcc100a has added support for this feature, but the NULL checks
weren't complete, only "handleAcquired" was checking if PerformanceStats
was supported before calling the API.
Extend the NULL checks to "handleAuthenticated" and "handleFailedAttempt"
calls as well.
