On all i2c-hid devices seen sofar the reset-ack either works, or the hw is somehow buggy and does not (always) ack the reset properly, yet it still works fine. Lower the very long reset timeout to 1 second which should be plenty and change the reset not getting acked from an error into a warning. This results in a bit cleaner code and avoids the need to add more I2C_HID_QUIRK_NO_IRQ_AFTER_RESET quirks in the future.
