Subject: [net 13/13] net/mlx5e: Fix failing ethtool query on FEC query error

From: Shay Agroskin <shayag@...lanox.com>

If FEC caps query fails when executing 'ethtool <interface>'
the whole callback fails unnecessarily, fixed that by replacing the
error return code with debug logging only.

Fixes: 6cfa94605091 ("net/mlx5e: Ethtool driver callback for query/set FEC policy")
