With the recent change to use bridge/port multicast context pointers
instead of bridge/port I missed to convert two locations which pass the
port pointer as-is, but with the new model we need to verify the port
context is non-NULL first and retrieve the port from it. The first
location is when doing querier selection when a query is received, the
second location is when leaving a group. The port context will be null
if the packets originated from the bridge device (i.e. from the host).
The fix is simple just check if the port context exists and retrieve
the port pointer from it.
