Validates that removal of VLAN doesn't impact sub-port RIF with same VLAN ID.
Test steps:
1.) Setup correct configuration of sub-ports on the DUT.
3.) Create a VLAN RIF with the same VLAN ID of sub-port.
4.) Added PortChannel interface to VLAN members.
5.) Delete a VLAN RIF.
6.) Make sure sub-port is available in redis-db.
7.) Verify that DUT sends ICMP reply packet to PTF.
8.) Clear configuration of sub-ports on the DUT.
9.) Clear configuration of sub-ports on the PTF.
Pass Criteria:
1.) Sub-port is available in redis-db.
2.) PTF gets ICMP reply packet from DUT.
