pim6d: (*,G) mroutes not learnt after pim6d daemon restart

Browse Source 
After restart pim dr address was zero due to which pim (*,G) join
could not get propagated towards RP.

While trying to find primary address ll_highest will be zero initially,
since we have not received address from zebra yet.

So we can get the best address at this point and use it as primary address
whenever ll_highest is zero.

Fixes: #11925
