drivers/net: fix unresolved 64bit math in mellanox/mlx4/en_dcb_nl.c 



Commit 109d2446

    "net/mlx4_en: Set max rate-limit for a TC"

introduced 64 bit math operations into mlx4_en_dcbnl_ieee_setmaxrate()

causing the following final link failure on an x86_32 allmodconfig

  ERROR: "__udivdi3" [drivers/net/ethernet/mellanox/mlx4/mlx4_en.ko] undefined!

Convert it to use div_u64() instead.
