hw/block/nvme: fix allocated namespace list to 256
Expand allocated namespace list (subsys->namespaces) to have 256 entries which is a value lager than at least NVME_MAX_NAMESPACES which is for attached namespace list in a controller. Allocated namespace list should at least larger than attached namespace list. n->num_namespaces = NVME_MAX_NAMESPACES; The above line will set the NN field by id->nn so that the subsystem should also prepare at least this number of namespace list entries.
