Subject: net/mlx5: E-Switch, Create a dedicated send to vport rule deletion
 function
Patch-mainline: v4.16-rc1
Git-commit: 159fe63922450183931429ef0b6c7548d49e5bcc
References: bsc#1103990 FATE#326006

In order for representors to send packets directly to VFs we use an
E-Switch function which insert special rules into the HW. For symmetry
create an E-Switch function that deletes these rules as well.
