For OUT endpoints, zero-length transfers require MaxPacketSize buffer as per the DWC_usb3 programming guide 3.30a section 4.2.3.3.

This patch fixes this by explicitly checking zero length transfer to correctly pad up to MaxPacketSize.

Fixes: c6267a51639b (usb: dwc3: gadget: align transfers to wMaxPacketSize)

Please enclose the summary in (""), no just (). And please never wrap it.
