Subject: net/failsafe: fix error string after ownership call
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9df324ad0895d8d41e020675a6abb020a84fe323;p=dpdk.git

net/failsafe: fix error string after ownership call

Ownership API returns a negative value, strerror expects a valid errno
value, thus positive.

Coverity issue: 260401
Fixes: dcd0c9c32b8d ("net/failsafe: use ownership mechanism for slaves")
