elevator: fix double release of elevator module
Our issue is descripted in below call path:
->elevator_init
->elevator_init_fn
->{cfq,deadline,noop}_init_queue
->elevator_alloc
->kzalloc_node
fail to call kzalloc_node and then put module in elevator_alloc;
fail to call elevator_init_fn and then put module again in elevator_init.
Remove elevator_put invoking in error path of elevator_alloc to avoid
double release issue.
