nvethernet: Disable VLAN VID tag filters

Browse Source 
Issue:
The L2 Orin bridge use case is encountered
an issue on AV+L NDAS builds for VLAN ping
from HOST1 to HOST2 over L2 Orin bridge.
As HOST1/HOST2 VLAN packets are dropped
by EQOS/MGBE MAC due to VLAN VID feature enable.

Fix:
To support the L2 Orin bridge VLAN
HOST1 to HOST2 data usecase, disable
the VLAN VID filters in the nvethernet driver.

Bug 4230250
