[ Upstream commit e0a312629fefa943534fc46f7bfbe6de3fdaf463 ]
Hendrik reported routes in the main table using source address are not removed when the address is removed. The problem is that fib_sync_down_addr does not account for devices in the default VRF which are associated with the main table. Fix by updating the table id reference.
