Refine ANA state from per subsystem listener to per subsystem listener
per ANA group.
Add an array of ANA state per ANA group to subsystem listener. The array is
indexed by ANA group ID - 1.
Then in I/O paths, we get ANA state by
ctrlr->listener->ana_state[ns->anagrpid - 1].
The NVMe specification indicates the existence of NVM subsystem specific
ANA state when FFFFFFFFh is specified as NSID for the Get Features
and the Set Features commands. For these, we return the optimized state.
Update the nvmf_subsystem_get_listeners RPC to return all ANA states
of the underlying ANA groups. The nvmf_subsystem_get_listeners RPC is
not matured and not used in the test code yet. Hence compatibility is
not high priority.
