net: ipmr: add getlink support

Currently there's no way to dump the VIF table for an ipmr table other than the default (via proc). This is a major issue when debugging ipmr issues and in general it is good to know which interfaces are configured. This patch adds support for RTM_GETLINK for the ipmr family so we can dump the VIF table and the ipmr table's current config for each table. We're protected by rtnl so no need to acquire RCU or mrt_lock.
