HID: constify params and return value of fetch_item()

Browse source

fetch_item() does not modify the descriptor it operates on.
As a prerequisite for the constification of hid_driver::dev_rdesc,
mark the parameters and return value of fetch_item() as const.

Also adapt the variable types in the callers to match this
constification.
