USB: ati_remote.c: autorepeat fix

When HZ is set to 250 (new default) or 100, the time span during which
repeated events from the device are ignored could be too small due to
ms->jiffies rounding.  This causes the auto repeat to kick in early making
it impossible for the user to generate individual press/release events.
Increate the timeout to compensate.
