zebra: Fix crash when OOM happens.
The hash key function choosen for mac vni's would tend
to clump the key value to the same number. Use a better
hash key generator to spread the hash values out.
A bad hash key might lead to O(2^n) memory consumption
because the hash size is doubled, each time a backet
exceeds a predefined threshold. This quickly leads
to OOM. Fixing this issue by fixing the hash
key generation to actually spread the keys out.
