accel/habanalabs: abort device reset for consecutive heartbeat failures
The mechanism of aborting device reset for consecutive fatal errors is
currently only for fatal errors that are reported by FW.
A non-responsive FW and consecutive heartbeat failures is also
considered fatal, so add them as well to this mechanism to avoid
recurring device reset in such a case.
