TODO: remove debugging printk's

This patch exports bridge multicast database via netlink
message type RTM_GETMDB. Similar to fdb, but currently bridge-specific.
We may need to support modify multicast database too (RTM_{ADD,DEL}MDB).

Minor nit reported by checkpatch was the messages should be using the api
which provides the most info in the log to identify.

WARNING: Prefer netdev_info(netdev, ... then dev_info(dev, ... then pr_info(...  to printk(KERN_INFO ...
#190: FILE: net/bridge/br_mdb.c:28:
+		printk(KERN_INFO "no router on bridge\n")

There is a set of macro's already for use in bridging code:
                br_info(br, "no router on bridge\n");
