usb: gadget: s3c-hsotg: pass 'struct usb_request *' to usb_gadget_unmap_request()

'struct usb_request *' should be passed to usb_gadget_unmap_request(),
as the second argument; however, 'struct s3c_hsotg_req *' is used.

Fixed build warnings as below:

drivers/usb/gadget/s3c-hsotg.c:440:2: warning: passing argument 2 of 'usb_gadget_unmap_request' from incompatible pointer type
