usb: gadget: net2280: unconditionally reset dma in usb_reset
If ep->dma is set, abort_dma() takes care of dma clean-up. If ep->dma is not set, unconditionally reset dma channel. Tested-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Signed-off-by: Mian Yousaf Kaukab <yousaf.kaukab@intel.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
