net: Improve simple_tx_hash().
Based upon feedback from Eric Dumazet and Andi Kleen.
Cure several deficiencies in simple_tx_hash() by using
jhash + reciprocol multiply.
1) Eliminates expensive modulus operation.
2) Makes hash less attackable by using random seed.
3) Eliminates endianness hash distribution issues.
