pimd: prevent unconditional SG join sends
It was causing a Join on (S,G) who's prune state was being cleared. This
was an inactive (KAT not running; no immediate OIL) entry that was being
flushed out but because of this incorrect Join (that was being done with
out join-state checks) the source was getting populated repeatedy i.e.
never aged.
Output of "ip monitor mroute"

These mroute events (on a no longer existing multicast souce) continue in
a never ending loop.
Triggered joins/prunes MUST only done via state machine transitions i.e.
via pim_upstream_update_join_desired.
