fib: Add some path-list flags to its key
Type: fix Ticket: 1729 The flags that are permanently set on a path-list should form part of its key in the path-list DB. Otherwise, if shared, they will not behave as expected. Change-Id: I0aa7c7c5d270c97b08014e4a47ddbdcee2358706 Signed-off-by: Neale Ranns <nranns@cisco.com> (cherry picked from commit 80d1ef96f92c15f4fd357af9845a0a3c602c2ffe)
