usb: gadget: f_loopback: eliminate abuse of ep->driver data

Browse source

Since ep->driver_data is not used for endpoint claiming, neither for
enabled/disabled state storing, we can reduce number of places where
we read or modify it's value, as now it has no particular meaning for
function or framework logic.

In case of f_hid we only need to store in ep->driver_data pointer to
struct f_loopback, as it's used in loopback_complete() callback. All
other uses of ep->driver_data are now meaningless and can be safely
removed.
