pimd: Dissallow query to be received from a non-connected source

When we receive an igmp query on a interface, ensure that the
source address of the packet is connected to the incoming
interface.  This will prevent a meanie from crafting a igmp
packet with a source address less than ours and causing
us to suspend query activities.

Fixes: #1692
