pimd, pim6d: Fix rp-info OIF having PIM disabled interface

Problem:
frr(config)# show ip pim rp-info
RP address group/prefix-list OIF I am RP Source Group-Type
109.0.0.3 224.0.0.0/4 ens192 no Static ASM

frr(config)# int ens192
frr(config-if)# no ip pim

frr(config) show ip pim rp-info
RP address group/prefix-list OIF I am RP Source Group-Type
109.0.0.3 224.0.0.0/4 ens192 no Static ASM

rp-info OIF is still having ens192 which is PIM disabled.
Fixing this as part of this PR.
