net: openvswitch: use div_u64() for 64-by-32 divisions
Compile the kernel for arm 32 platform, the build warning found.
To fix that, should use div_u64() for divisions.
| net/openvswitch/meter.c:396: undefined reference to `__udivdi3'
[add more commit msg, change reported tag, and use div_u64 instead
of do_div by Tonghao]
