SupplicantStaIfaceHal: Don't trigger onDeath for remote exception
When supplicant is abruptly killed, any ongoing hwbinder transactions
will raise remote exceptions. The handling of these remote exceptions
might happen before the death notification from hwservicemanager is
processed. To prevent multiple death notifications, don't trigger the
onDeath callback on remote exception handling. Remote exception handling
will just clear internal state and wait for the death notification from
the system to trigger the onDeath callback.
Remote exceptions encountered in the initialization path will still
trigger death notification because we may not get notified from the
service manager.
Bug: 79532177
Test: Unit tests
Test: Crash wpa_supplicant in a loop and ensure that only one death
notification is triggered per crash.
