[dpdk-dev] [PATCH 4/4] devtools: fix direct additions to stable API

[David Marchand <david.marchand@redhat.com>]

The incriminated commit broke the detection of new symbols skipping the
EXPERIMENTAL step before entering a stable abi section.
sed won't return an error, check a null output instead.

Fixes: 3630757803ab ("devtools: accept experimental symbol promotion")
Cc: stable@dpdk.org
