HID: fix autocentering of PID devices

When setting the autocentering of PID devices, PID_DIRECTION_ENABLE is not
being explicitely set to 1. This results in autocentering working only on the
vertical axis when this field is preset to 0.

Fix that by setting it explicitely to 1 when preparing the set_effect report
for autocentering spring effect.
