Ming Lei 2bfdbe8b7e null_blk: allow zero poll queues 
There isn't any reason to not allow zero poll queues from user
viewpoint.

Also sometimes we need to compare io poll between poll mode and irq
mode, so not allowing poll queues is bad.

Fixes: 15dfc662ef ("null_blk: Fix handling of submit_queues and poll_queues attributes")
