wifi: Extend onFailure callback for dual AP case

There are two AP instances when a bridged mode AP is running.
Extend onFailure callback to support bridged mode cases.
So if there is a problem in one of the instances, the framework
can handle the failure separately. (i.e. No need to shutdown the
whole Soft Ap).

Bug: 188921389
Test: Test with test code, the callback works normally.
