lib/env_dpdk: warn about deprecated API



__rte_experimental attribute in DPDK ends up being changed to
'deprecated'. See rte_compat.h in DPDK.

Goal of patch below was to allow SPDK to use experimental API
"(b6fce191) env/dpdk: add support for DPDK 18.05 dynamic memory allocation"

Yet it disabled warnings for both. This patch makes it so that
__rte_experimental will not produce warnings, but deprecations in DPDK
will.

It will help identify incoming changes when testing newer versions
of DPDK in the future.
