bdev/nvme: Separate attach_cb between creating ctrlr and setting failover

The NVMe bdev module will have two similar features, multipath and
failover when it supports multipath.

Take a case that we add two different trids with the same name by the
bdev_nvme_attach_controller RPC as an example.

The failover adds secondary trid to an existing nvme_ctrlr. The multipath
feature creates another nvme_ctrlr and adds it to the same nvme_bdev_ctrlr
which has an existing nvme_ctrlr.

We want to use bdev_nvme_attach_controller for both failover and multipath.
To do it cleanly, separate callback to spdk_nvme_connect_async() between
creating ctrlr and setting failover.

bdev/nvme: Read ANA log page itself when nvme_ctrlr is created

If ctrlr supports ANA log page, nvme_ctrlr allocates a buffer for ANA
log page and read ANA log page itself, and then each nvme_ns sets its
ANA state by parsing ANA log page.

Most code was brought from NVMe driver because NVMe driver already
supports ANA log page management. However it had a bug that assumed
each descriptor is 8-bytes aligned. Fix the bug together in this
patch. Besides, the implementation in NVMe driver was synchronous.
NVMe bdev module reads ANA log page asynchronously instead.

The next patch will support ANA log page update by AER handler.

bdev/nvme: Rename nvme_io_path by nvme_ctrlr_channel

We will name the lower level objects starting with nvme_* and the
upper level objects starting with nvme_bdev_*.

This object is a channel per ctrlr and another new channel will be
added on top of this object.

Rename nvme_io_path by nvme_ctrlr_channel based on the new naming rule.

nvme_io_path will be used for a new object which is used to find an
optimal I/O path and to reset multiple ctrlrs sequentially when
multipath is supported.
