can: pch_can: pch_can_rx_normal: fix use after free
commit 94cddf1e9227a171b27292509d59691819c458db upstream.
After calling netif_receive_skb(skb), dereferencing skb is unsafe.
Especially, the can_frame cf which aliases skb memory is dereferenced
just after the call netif_receive_skb(skb).
Reordering the lines solves the issue.
Fixes: b21d18b51b31 ("can: Topcliff: Add PCH_CAN driver.")
