Shuhei Matsumoto c19ec84378 bdev/nvme: Add multiple namespaces to a single nvme_bdev
This patch removes the critical limitation that ctrlrs which are
aggregated need to have no namespace. After this patch, we can
add multiple namespaces into a single nvme_bdev.

The conditions that such namespaces satisfy are,
- they are in the same NVM subsystem,
- they are in different ctrlrs,
- they are identical.

Additionally, if we add one or more namespaces to an existing
nvme_bdev and there are active nvme_bdev_channels, the corresponding
I/O paths are added to these nvme_bdev_channels.

Even after this patch, ANA state is not utilized in I/O paths yet.
It will be done in the following patches.
