net/mlx5: fix TPID check for VLAN push action on E-Switch

Browse Source 
The VLAN push action on E-Switch supports only 802.1Q (0x8100)
and 802.1AD (0x88A8) Tag Protocol ID (TPID) insertions. The
parameter check for RTE_FLOW_ACTION_TYPE_OF_PUSH_VLAN action
is added.

Fixes: 57123c00c1b8 ("net/mlx5: add Linux TC flower driver for E-Switch flow")
