ospfd: Do not always debug joining AllDRouters Multicast group

My log file is filling up with:
2022-11-26 13:24:47.532 [DEBG] ospfd: [RY794-DQ7AK] interface 192.168.119.229 [2] join AllDRouters Multicast group.

Every 1/2 hour.  There is nothing an operator needs to do here and nothing
that they can change.  Let's guard this output.
