env_dpdk: modify error message when DPDK already initialized



Ideally we'd have a way to query if DPDK is already
initialized but we don't have that yet.  We want that
for the case where we have an SPDK application that's part
of a framework that may (or may not) have already initialized
DPDK.  If it's already been initialized, let's print an
error message that isn't quite as inflammatory.
