This is the style used through most of the SPDK code, but several

In principle, we should not have active tasks, which means
that lun->tasks should be empty. But for the exceptional case,
we may still need to handle those active tasks, to make
the scsi related application continue running instead of quit.
We should not directly call spdk_scsi_lun_complete_task since
those tasks are already sent to bdev layer. And finally, those
tasks will be return (even aborted) by call backs. So we only need to
set task status to condition, but
not call spdk_scsi_lun_complete_task directly.

Struct spdk_scsi_lun has the claimed flag as a member.
However the claimed flag is no longer required.
Moreover the claimed flag itself is not used but
spdk_scsi_lun_claim() and _unclaim() functions are used in the
UT code by hard to understand manner. Moving the logic into
spdk_scsi_lun_construct() and _destruct() in the UT code will
be more natural.
Hence remove the claimed flag from LUN and do a little refactoring
in the UT code.

However, the current code was assuming that LUN 0 had to be in the first
array element of lun_id_list in spdk_scsi_dev_construct(). Combined
with the scripts/rpc.py implementation that uses a Python (unordered)

where LUN 0 exists in the list but isn't first.
Fix the check by allowing LUN 0 in any position of the lun_id_list

Reset semantics are still that they affect the entire bdev
and not just the channel it was submitted on.

1) Consolidate the checks for a null LUN
2) Eliminate a bunch of static functions that are no
longer needed due to #1
This prepares for some upcoming bdev reset changes.

The user should not see the bdev_io status directly; the NVMe and SCSI
error code wrappers provide the ability to translate to the desired
format regardless of what kind of error is stored inside the bdev_io.
Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.

Specify the function as a parameter to spdk_scsi_dev_queue_mgmt_task.
This makes the API clearer by making it explicit that the management
function is required for management tasks.
