With the latest 201911 image, the following error was seen on staging devices with TSB command ( for both single asic, multi asic ). Though this err message doesn't affect the TSB functionality, it is good to fix.

admin@STG01-0101-0102-01T1:~$ TSB
BGP0 : % Could not find route-map entry TO_TIER0_V4 20
line 1: Failure to communicate[13] to zebra, line: no route-map TO_TIER0_V4 permit 20
% Could not find route-map entry TO_TIER0_V4 30
line 2: Failure to communicate[13] to zebra, line: no route-map TO_TIER0_V4 deny 30

In addition, in this PR I am fixing the message displayed to user when there are no BGP neighbors configured on that BGP instance. In multi-asic device there could be case where there are no BGP neighbors configured on a particular ASIC.
