IPv4: unresolved multicast route cleanup
Fixes the expiration timer for unresolved multicast route entries.
In case new multicast routing requests come in faster than the
expiration timeout occurs (e.g. zap through multicast TV streams), the
timer is prevented from being called at time for already existing entries.
As the single timer is resetted to default whenever a new entry is made,
the timeout for existing unresolved entires are missed and/or not
updated. As a consequence new requests are denied when the limit of
unresolved entries has been reached because old entries live longer than
they are supposed to.
The solution is to reset the timer only for the first unresolved entry
in the multicast routing cache. All other timers are already set and
updated correctly within the timer function itself by now.
