660b044294 pimd: pim_ifchannel_local_membership_add should not inherit if (S,G) rpf unresolved 
Problem:
S,G entry has iif = oif in FHR is LHR case.

Setup:-

R11-----R2----R4

R11 :- FHR and LHR
R2 :- RP
R4 :- LHR

Issue :-

1) shut mapped interface in R11
2) wait for 5 min
3) do FRR restart
5) No shut of mapped interface

OIL is added for local interface also where OIL is same as IIF
and duplicate traffic observed on R4 receives in Ixia

RCA:
pim_ifchannel_local_membership_add adds inherited oif from starg when iif for
SG is unavailable.
When  rpf for that SG resolves to this inherited oif from starg, iif is also in oif.
This results in dup traffic.

Fix:
If iif is not available, do not inherit from starg.

40d038d2a1 lib: Change frrscript_call to call function instead 
There is some rather heavy error checking logic in frrscript_call. Normally
I'd put this in the _frrscript_call function, but the error checking needs
to happen before the encoders/decoders in the macro are called.

The error checking looks messy but its really just nested ternary
expressions insite a larger statement expression.

bf157b9263 zebra: fix ifp pointer for groups/recursives 
At some point we broke the ifp pointer for nhe->ifp such
that it was pointing to an interface even in groups/recurisve
instances.

Add checks here to make it again so that we only set the ifp
pointer if it is a fully resolved singleton NHE.

b59839af7d zebra: When passing lookup information back pass the fully resolved 
In the reachability code we auto pass back the fully resolved
nexthops.  Modify the ZEBRA_IPV4_NEXTHOP_LOOKUP_MRIB code
to do the exact same thing so that the zclient_lookup_nexthop

zebra already has.
