Subject: [PATCH] usb: gadget: rndis: don't test against req->length

commit 472b91274a6c6857877b5caddb875dcb5ecdfcb8 upstream.

composite.c always sets req->length to zero
and expects function driver's setup handlers
to return the amount of bytes to be used
on req->length. If we test against req->length
w_length will always be greater than req->length
thus making us always stall that particular
SEND_ENCAPSULATED_COMMAND request.

Tested against a Windows XP SP3.
