Dmitry Torokhov 9a83563fb3 HID: hiddev: use hid_hw_power instead of usbhid_get/put_power
Instead of calling into usbhid code directly, let's use the standard
accessors for the transport HID drivers, and stop clobbering their error
codes with -EIO.

This also allows us to remove usbhid_get/put_power(), leaving only
usbhid_power().
