pimd: clear upstream rpf information when RP becomes not reachable
When route to RP gets modified, FRR receives a notification from
zebra, and call the function pim_resolve_upstream_nh() to compute the
nexthop and update upstream->rpf structure.
Issue: In case when RP becomes not reachable, FRR only uninstall
the mroute from the kernal, but not update the upstream->rpf structure.
Fix: When FRR receives a notification from zebra saying RP becomes
not reachable, then update the following fields.
1. update channel_oil incoming interface as MAXVIFS
2. Un-install the mroute from the kernel.
3. Switch upstream state from JOINED to NOTJOINED.
4. Clear the nexthop information of the upstream.
