bgpd: Fix leaked memory when showing some bgp routes
The two memory leaks:

For the 1st one, if the operator issues a advertised-routes command, the
json_ar variable was never being freed.
For the 2nd one, if the operator issued a command where the
output_count_per_rd is 0, we need to free the json_routes value.
