BUG/MAJOR: sched: make it work also when not building with DEBUG_STRICT

Browse Source 
Sadly, the fix from commit 54d31170a ("BUG/MAJOR: sched: make sure
task_kill() always queues the task") broke the builds without DEBUG_STRICT
as, in order to be careful, it plcaed a BUG_ON() around the previously
failing condition to check for any new possible failure, but this BUG_ON
strips the condition when DEBUG_STRICT is not set. We don't want BUG_ON
to evaluate any condition either as some debugging code calls possibly
expensive ones (e.g. in htx_get_stline). Let's just drop the useless
BUG_ON().

No backport is needed, this is 2.2-dev.
