USB: net2280: don't send unwanted zero-length packets
The net2280 driver is too eager to send zero-length packets when IN tokens are received on ep0. No such packet should be sent (the driver should NAK) before the gadget driver has queued the proper response. Otherwise deferred responses are impossible. This patch (as823) makes net2280 avoid sending ZLPs for IN transfers on ep0 until a response has been submitted, and avoids stalling when an OUT packet is received before a request has been submitted for an OUT transfer on ep0.
