wil6210: use after free in wil_netif_rx_any()
The debug code dereferences "skb" to print "skb->len" so we have to print the message before we free "skb". Fixes: f99fe49ff372 ("wil6210: add wil_netif_rx() helper function") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
