[net 06/11] net/mlx5e: Return error if prio is specified when offloading eswitch vlan push

[Saeed Mahameed]

From: Or Gerlitz <ogerl...@mellanox.com>

This isn't supported when we emulate eswitch vlan push action which
is the current state of things.

Fixes: 8b32580df1cb ('net/mlx5e: Add TC vlan action for SRIOV offloads')
