rt2x00: Fix double usage of skb->cb in USB RX path.
It is not safe to use the skb->cb area for both the rxd and
skb_frame_desc data at the same time, while they occupy an overlapping
piece of memory. This can lead to hard to trace crashes as pointers
within skb_frame_desc are pointing into nowhere, or the rxd data is
overwritten with non-sense.
Fix it by copying the rxd to a small buffer on the stack.
