Subject: net/mlx5e: Avoid overriding the user provided priority for offloaded
 tc rules
Patch-mainline: v4.20
Git-commit: d14f6f2a84326dd2751962167b2293fc91751ff8
References: bsc#1103990 FATE#326006

Just a leftover which was wrongly left there, remove it while spawning
a message to suggest firmware upgrade.
