This avoids having to dereference the spdk_bdev_io's
channel in the spdk_bdev_free_io() path.
Cleaning up after hotplug events should ensure that
all associated bdev_ios have been freed (not just
completed) before the bdev channels have been freed,
but this patch gives us some more wiggle room in this
area.
Results in a small (1-2%) performance degradation on
a bdevperf microbenchmark, but should result in no
noticeable difference on any real world workload.

There is no need to keep a lun name anymore - we always
use the bdev name as the lun name so it is not providing any
additional value. This also keeps us from associating
the same bdev with different LUNs on different iSCSI target
nodes or vhost-scsi controllers.
Side effect of this change is:
1) Use "bdev_name" across the APIs to make it more clear
what these names refer to.

Splitting an iSCSI task into primary and sub tasks is complex
operation and a degradation was caused for it.
Hence adding test codes is required but there is no UT code for
it yet.
primary->bytes_completed is for read completion from bdev and
it is tested by this patch.
Additional test codes will follow:
- primary->bytes_completed is tested when read tasks do not
complete in order.
- primary->task.data_transferred is for write completion to
initiator through network.
- primary->task.data_transferred is tested by another patch
because primary->bytes_completed is used in iscsi/conn.c but
primary->task.data_transferred is used in iscsi/iscsi.c.

In a couple of invalid-request error conditions
we still write the VIRTIO_BLK_S_UNSUPP response while
