pimd: send an immediate XG JP message when switching from SPT to RPT
Today we are only pruning the SPT when (S,G) upstream entry
switches from Joined toNotJoined. This leaves the source still
pruned along the RPT till the next periodic XG join-prune is sent
to the RPF(RP). Traffic from the source will be blackholed for this
duration. To prevent that we need send a new JP message
to RPF(RP) immediately.
