can: mcba_usb: mcba_usb_start_xmit(): first fill skb, then pass to can_put_echo_skb()
[ Upstream commit 81c9c8e0adef3285336b942f93287c554c89e6c6 ]
The driver has to first fill the skb with data and then handle it to
can_put_echo_skb(). This patch moves the can_put_echo_skb() down, right before
sending the skb out via USB.
Fixes: 51f3baad7de9 ("can: mcba_usb: Add support for Microchip CAN BUS Analyzer")
