There is a piece of sanity checks code in the put_unbound_pool(). The meaning of this code is "if it is not an unbound pool, it will complain and return" IIUC. But the code uses "pool->flags & POOL_DISASSOCIATED" imprecisely due to a non-unbound pool may also have this flags.
We should use "pool->cpu < 0" to stand for an unbound pool, so we covert the code to it. There is no strictly wrong if we still keep "pool->flags & POOL_DISASSOCIATED" here, but it is just a noise if we keep it: 1) we focus on "unbound" here, not "[dis]association". 2) "pool->cpu < 0" already implies "pool->flags & POOL_DISASSOCIATED".
