bgpd: fix do not export VPN prefix when no SID available on the VRF
When detaching the locator from the main BGP instance, the used SIDs
and locators are removed from the srv6 per-afi or per-vrf contects.
Under those conditions, it is not possible to attempt to export new
VPN updates. Do invalidate the nexthop for leaking.
Restrict the control for exported VPN prefixes and not for unicast
imported prefixes.
