Don't update old_vals when not in EVDEV_RELATIVE_MODE
When not in EVDEV_RELATIVE_MODE, absolute position is stored in old_vals. This serves
no purpose except that old_vals is ready when the device is switched to
EVDEV_RELATIVE_MODE. It is however better to make the copy between old_vals
and abs_vals at the time of the switch rather than all the time.
