Minor refactor fabric.p4
Remove origin_ether_type from fabric.p4
We can use ether_type from VLAN header since ingress_port_vlan table
always push a VLAN header to the packet if there is no VLAN header.
For configured interface, there exists flow rules to push VLAN.
For ports which not configured (infrastructure ports), the segment routing
application installs a rule which pushed internal VLAN to the packet (4094)
