Fix fail_timer duration multiplication

[slqy123]

Remove incorrect * 1000 multiplier in fail_timer.Check() call.

When the PeriodClock API was migrated to std::chrono in commit 4011899 , the fail_timer.Check() call was not updated. This caused the timer to check for a duration that was 1000 times longer than intended.

// before
static constexpr unsigned REOPEN_AFTER = 10;
// after
static constexpr PeriodClock::Duration REOPEN_AFTER = std::chrono::seconds(10);

// It actually waits 10000 seconds
fail_timer.Check(REOPEN_AFTER * 1000);

Yes. This may fixes #361, #1630 (maybe? I still get playing silence to avoid xrun while debugging, but the stream reconnects successfully after the retry delay)
