Toke Høiland-Jørgensen 05679ca6fe xdp: Prevent overflow in devmap_hash cost calculation for 32-bit builds 
Tetsuo pointed out that without an explicit cast, the cost calculation for
devmap_hash type maps could overflow on 32-bit builds. This adds the
missing cast.

Fixes: 6f9d451ab1 ("xdp: Add devmap_hash map type for looking up devices by hashed index")
