pimd, pim6d: Update upstream rpf disable/enable pim on interface

Problem:
When "no ip pim" is executed on source connected interface, its
ifp->info is set to NULL. But KAT on this interface is still
running, it wrongly dereferences NULL. This leads to crash.

Root Cause:
pim upstream IIF is still pointing towards the source connected
interface which is not pim enabled and Mroute is still present in
the kernel.

Fix:
When “no ip pim” command gets executed on source connected interface,
then loop through all the pnc->nexthop, if any new nexthop found,
then update the upstream IIF accordindly, if not found then update
the upstream IIF as Unknown and uninstall the mroute from kernel.

When “ip pim” command gets executed on source connected interface,
then also loop through all the pnc->nexthop  and update the upstream IIF,
install the mroute in kernel.
