pim6d: Clear channel_oil on prune
Receiver---LHR---RP
Problem:
In LHR, ipv6 pim state remains after MLD prune received.
Root Cause:
When LHR receives join, it creates (*,G) channel oil with
oil_ref_count = 2. The channel_oil is used by gm_sg sg->oil
and upstream->channel_oil.
When LHR receives prune, currently upstream->channel_oil is
deleted and gm_sg sg->oil still present. Due to this channel_oil
is still present with oil_ref_count = 1
Fix:
When LHR receives prune, upstream->channel_oil and pim_sg sg->oil
needs to be deleted.
Issue: #11249
