Bug Description

While deploying VMX VM's, we have noticed that, tunnel communication across compute nodes is dropping the Multicast/Broadcast packets.

Here are the setup details in reproduced state. FPC0 VM is trying to send broadcast packets to RE VM, which are getting dropped at VRF level on its compute node.

Multicast traffic gets dropped.

Problem:
When all the VMI's are gone multicast object is deleted. However VN is still not
gone and meanwhile new VMI gets added. During this window where all VMI were
gone to new VMI gets added, olist for replication tree is received from
control-node. This update is neglected in absence of multicast object for same.
This results in no multicast tree.

Solution:
Retain multicast object till two conditions are met:
- All VMIS are gone
- VN is no more in use by multicast.
