pimd: Handling Null incoming interface of dummy upstream
When FRR receives IGMP/PIM (*, G) join and RP is not configured or not
reachable, then we are creating a dummy upstream with incoming interface
as NULL and upstream address as INADDR_ANY.
Added upstream address and incoming interface validation where it is necessary,
before doing any operation on the upstream.
