[dpdk-dev] [PATCH 3/4] raw/skeleton_rawdev: fix warnings with GCC 9 on Fedora 30

[Bruce Richardson <bruce.richardson@intel.com>]

GCC9 gives warnings if the parameter passed to printf for "%s" could be
NULL, so we need to add checks in some cases to ensure that is not the
case.

Fixes: 61c592a8d035 ("raw/skeleton: introduce skeleton rawdev driver")
