net/mlx5e: Fix error handling when refreshing TIRs

[ Upstream commit bc87a003 ]

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.
