bgpd: fix default RD value in running-cfg

When bgp vrf is configured with non-default
RD value, config flag is set.
Upon removing non-default RD value the flag was not reset,
thus displayed default RD value in running-config.

router bgp 5550 vrf vrf1
 rd 45.0.2.2:5

Unset the RD configuration flag under bgp_vrf instance.
