Vincent Mailhol 5408824636 can: peak_usb: fix use after free bugs
[ Upstream commit 50aca891d7a554db0901b245167cd653d73aaa71 ]

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: 0a25e1f4f185 ("can: peak_usb: add support for PEAK new CANFD USB adapters")
