On 32-bit architectures, both skb_queue_len() and SKB_TRUESIZE(0) evaluate
to 32-bit values. The multiplication can overflow before being assigned to
the u64 skb_overhead variable, making the skb overhead check ineffective.
Cast skb_queue_len() to u64 so the multiplication is always performed in
64-bit arithmetic.
