Ticket: CM-11327 Signed-off-by: Don Slice Reviewed-by: Donald Sharp
Testing Done: Manual testing, bgp-min, vrf-min, bgp-smoke, vrf-smoke all successful
When bgp was configured in a vrf and then deleted, the vrf->iflist
was being deleted from the vrf. Since the vrf itself was not deleted,
it was assumed in later calls that the vrf->iflist was still there
and when it was referenced, the crash occurred.
