can: peak_usb: fix potential double kfree_skb()
commit fee6a8923ae0d318a7f7950c6c6c28a96cea099b upstream.
When closing the CAN device while tx skbs are inflight, echo skb could
be released twice. By calling close_candev() before unlinking all
pending tx urbs, then the internal echo_skb[] array is fully and
correctly cleared before the USB write callback and, therefore,
can_get_echo_skb() are called, for each aborted URB.
