hw/block/nvme: support namespace detach
Given that now we have nvme-subsys device supported, we can manage
namespace allocated, but not attached: detached. This patch introduced
a parameter for nvme-ns device named 'detached'. This parameter
indicates whether the given namespace device is detached from
a entire NVMe subsystem('subsys' given case, shared namespace) or a
controller('bus' given case, private namespace).
- Allocated namespace
1) Shared ns in the subsystem 'subsys0':
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,subsys=subsys0,detached=true
2) Private ns for the controller 'nvme0' of the subsystem 'subsys0':
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true
3) (Invalid case) Controller 'nvme0' has no subsystem to manage ns:
-device nvme,serial=foo,id=nvme0
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true
