[PATCH v4 1/2] lpm: add const to lpm arg of rte_lpm_lookup

[Stanislaw Kardach <kda@semihalf.com>]

All other rte_lpm_lookup* functions take lpm argument as a const. As the
basic rte_lpm_lookup() performs the same function, it should also do
that.

As this function is inline, no API/ABI change happens.
