Vrf pending because of mpls label.

Problem:
MPLS label was pending pointing to Composite NH. This NH holds
reference to VRF. This label was programmed because adding EVPN path in multicast
route vxlan tag was added as ethernet identifier and label as well. When all
routes except evpn peer path is gone this vxlan tag (which was copied in label)
gets copied to master path which in turn tries to rebake NH for
this label.
EVPN mpls label should only be picked from local path or local vm peer path.

Solution:
Pass invalid label for evpn path.
