Log Message:
Fix reference leaks of llentry

callout_reset and callout_halt can cancel a pending callout without telling us.
Detect a cancel and remove a reference by using callout_pending and
callout_stop (it's a bit tricy though, we can detect it).

While here, we can remove remaining abuses of mutex_owned for softnet_lock.
