sched: add sanity check in partition_sched_domains()

Browse Source 
Impact: cleanup, add debug check

It's wrong to make dattr_new = NULL if doms_new == NULL, it introduces
memory leak if dattr_new != NULL. Fortunately dattr_new is always NULL
in this case. So remove the code and add a sanity check.
