bridge: Fix fatal typo in setup of multicast_querier_expired
Unfortunately it seems that I didn't properly test the case of
an expired external querier in the recent multicast bridge series.
The setup of the timer in that case is completely broken and leads
to a NULL-pointer dereference. This patch fixes it.
