bgpd: update mp_nexthop field in case mp-bgp entry is created

Browse Source 
In case a manual set of MPLS, ENCAP, or EVPN entry is set, then the
nexthop attribute localted in attr->extra structure must be changed too.
In standard cases, where IPv4 IGP nexthop address is picked up, the same
address ie chosen.
