Poking a bit on autotest revealed a few shortcomings in the lpm allocation path.
Thanks to the feedback to the first revision of the patches here v2.
Also Oliver Matz spotted similar issues and made me aware - thanks!
Integrating them revealed even more use after free / leak issues.

*updates in v3*
- lpm create/free path for v20 and v1604 got the same fixes that were
  already identified for lpm6 before

*updates in v2*
- lpm/lpm6 patches split
- following dpdk coding guidelines regarding single line if's
- adding singed-off and acked-bys gathered so far
- combine all three related patches in one series
