pimd: Fix WG/SGRpt & WG J/P processing

During processing of Join/Prune,
for a S,G entry, current state is SGRpt, when only *,G is
received, need to clear SGRpt and add/inherit the *,G OIF to S,G so
it can forward traffic to downstream where *,G is received.
Upon receiving SGRpt prune remove the inherited *,G OIF.

From, downstream router received *,G Prune along with SGRpt
prune. Avoid sending *,G and SGRpt Prune together.
Reset upstream_del reset ifchannel to NULL.

Testing Done:
Run failed smoke test of sending data packets, trigger SPT switchover,
*,G path received SGRpt later data traffic stopped S,G ages out from LHR, sends only
*,G join to upstream, verified S,G entry inherit the OIF.
Upon receiving SGRpt deletes inherited oif and retains in SGRpt state.
