Vincent Mailhol 50aca891d7 can: peak_usb: fix use after free bugs 
After calling peak_usb_netif_rx_ni(skb), dereferencing skb is unsafe.
Especially, the can_frame cf which aliases skb memory is accessed
after the peak_usb_netif_rx_ni().

Reordering the lines solves the issue.

Fixes: 0a25e1f4f1 ("can: peak_usb: add support for PEAK new CANFD USB adapters")
