From: Jan Altenberg <jan.altenberg@linutronix.de>

backport of 41566bcf35a8b23ce4715dadb5acfd1098c1d3e4

commit 0cf4f2de0a0f4100795f38ef894d4910678c74f8 introduced a bug, which
prevents sending an USB_CDC_GET_ENCAPSULATED_RESPONSE message. This
breaks the RNDIS initialization (especially / only Windoze machines
dislike this behavior...).
