[PATCH] examples/l3fwd: fix compilation when DP debug on

[Andrei-Niculae Petre <p31andrei@gmail.com>]

Previously, l3fwd example app would fail to compile ([1]) if one would
put RTE_LOG_DP_LEVEL=RTE_LOG_DEBUG in config/rte_config.h and try to
compile dpdk; this path was not enabled via compiling debug build
(--buildtype=debug) alone, but needed the data path to be at debug
level.
