Subject: net/mlx5: E-Switch, Fix drop counters use before creation
Patch-mainline: v4.16-rc3
Git-commit: 26a0f6e82997d5c8345782b55d3a7894421f777f
References: bsc#1103990 FATE#326006
First use of drop counters happens in esw_apply_vport_conf function,
while they are allocated later in the flow. Fix that by moving
esw_vport_create_drop_counters function to be called before the first use.
Fixes: b8a0dbe3a90b ("net/mlx5e: E-switch, Add steering drop counters")
