net/mlx5e: Return error if prio is specified when offloading eswitch vlan push

Browse Source 
[ Upstream commit 001a2fc0c8cc29241305e44ffbce52d1daf8782b ]

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')
