bgpd: clear l3vni prefix-only flag upon deletion

When L3vni is created with prefix-only flag,
the flag is set at bgp vrf instance level.
In the case of bgp instance is non auto created,
means user configured instance (i.e 'router bgp x vrf <name>')

Upon deletion of l3vni, clear the prefix-only flag from
bgp vrf instance.
