portable/nrf5x: complete zero-length bulk OUT transfers

2026-08-17T05:17:00Z

A zero-length OUT read (e.g. the MTP driver's read for the host's terminating data ZLP) could never complete when the ZLP's EPDATA arrived after the read was armed: actual_len < total_len is always false for total_len == 0, so the handler only set data_received and the armed transfer hung forever, wedging both bulk endpoints (host sees pure NAK; EP0 stays alive). Run the 0-byte DMA in that case to drain the endpoint and complete the transfer, matching what the arm path already does when the ZLP arrives first. Found via usbmon on the HIL rig: device/mtp on feather_nrf52840_express wedged after SendObject's terminating ZLP whenever the class armed the read before the host's (NAK-delayed) ZLP retry landed - deterministic under CI load, which is why PR CI only passed this test on a re-flash retry (21.4 s vs the normal 2.2 s).
