Subject: [PATCH][next] net/mlx5: fix missing assignment of variable err

From: Colin Ian King <[email protected]>

The error return from a call to mlx5_flow_namespace_set_peer is not
being assigned to variable err and hence the error check following
the call is currently not working. Fix this by assigning ret as
intended.

Addresses-Coverity: ("Logically dead code")

Applied to net-next-mlx5.

I have a cleanup series coming up, will send it all together to
net-next soon.

Thanks,
