[dpdk-dev] [PATCH v1] net/failsafe: fix strerror call in sub-eal

[Gaetan Rivet]

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

CID 260401:  Error handling issues  (NEGATIVE_RETURNS)
"ret" is passed to a parameter that cannot be negative.

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