[dpdk-dev] [PATCH] net/failsafe: fix failsafe bus uninit return value

[Raslan Darawsheh <rasland@mellanox.com>]

fs_bus_uninit is always returning 0 no matter what was the status
of each sub device bus_uninit value.

Will now return the first sub device fail value in case it fails.

Fixes: a46f8d58 ("net/failsafe: add fail-safe PMD")
