usb: gadget: Introduce usb_gadget_giveback_request()

Browse Source 
All USB peripheral controller drivers call completion routines directly.
This patch adds usb_gadget_giveback_request() which will be used instead
of direct invocation in the next patch. The goal here is to have a place
where common functionality can be added.
