Rootcause and fix: In mlag+pim, packets are software forwarded because the mroute is stuck in pimreg state in non-DR node. Align with RFC:avoid REG_JOIN on the mlag node that lost DR election. Gate pim_register_join() with pim_upstream_could_register() on the WRVIFWHOLE connected-source path. Signed-off-by: harini <hnattamaisub@nvidia.com> (cherry picked from commit beafaee)
