[PATCH] net/mlx5: fix device checking for send to kernel action

[Jiawei Wang]

The previous commit extended the send to kernel support on FDB table.
This action creation failed at MLX5 core kernel module, due to the
VF/SF ports do NOT belong to E-Switch mode.
The failure caused the kernel stuck with the older MLX5 core
kernel version.

This patch adds the checking to avoid creating action at the VF/SF ports
on the FDB table.

Fixes: b2cd39187cd4 ("net/mlx5: extend send to kernel action support")
