When cntlid_min is greater than cntlid_max,
goto wrong label, should be goto out_free_sqs
label. Otherwise there is a memory leak problem
on the nvmet_alloc_ctrl function().
Fixes: 94a39d61f80f ("nvmet: make ctrl-id configurable")
Fixes: 6d65aeab7bf6e ("nvmet: remove unused ctrl->cqs")

Looks good, except commit message could be better :-
When cntlid_min is greater than cntlid_max, goto wrong label, should be
goto out_free_sqs label. Otherwise there is a memory leak problem on the
nvmet_alloc_ctrl function().
Fixes: 94a39d61f80f ("nvmet: make ctrl-id configurable")

Thanks for your review. I will make the commit message better.
and I found the nvmet-loop has a similar issue,
will send patch series soon.
