Subject: net/mlx5e: Fix error handling when refreshing TIRs
From: Gavi Teitz <gavi@xxxxxxxxxxxx>
[ Upstream commit bc87a0036826a37b43489b029af8143bd07c6cca ]
Previously, a false positive would be caught if the TIRs list is
empty, since the err value was initialized to -ENOMEM, and was only
updated if a TIR is refreshed. This is resolved by initializing the
err value to zero.
