[dpdk-dev] [PATCH] app/testpmd: fix runtime dead code

[Michal Jastrzebski <michalx.k.jastrzebski@intel.com>]

From: Tomasz Kulasek <tomaszx.kulasek@intel.com>

Coverity reports DEADCODE, as assumes that RTE_LIBRTE_I40E_PMD
is defined and function compiles entirely. 
The fix is about to place printf function into #else branch
of conditional compilation, since it is known at compile
time if i40e is supported. No need to check it at runtime. 

Coverity issue: 158646
Fixes: 37a56cce7b8e ("app/testpmd: enable DDP get info feature")
