This is no longer used anywhere. For the places where we previously
used it, we've since found alternate solutions that do not
require it.

An ECN to the NVMe 1.3 specification has clarified that the NQN may
contain 223 bytes before the null terminator. Make all of our NQN
length checks consistently enforce this behavior.

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.

The SCSI library already provides a callback when the task is released
(free_fn), so the user can update their own task counter.

The SCSI layer was not using the task ID for anything; the iSCSI layer
was using it to store the task tag, so move it there and rename it to
"tag" to make its purpose clear.

In the pattern set by spdk_bdev_io_complete_nvme_status(), allow
blockdev modules to complete a bdev_io with a SCSI status code.
Also move it to the internal bdev header file, since only bdev modules
should be setting bdev_io status codes.

The VirtualBox emulated NVMe device will intermittently
hang on the first read/write command after an I/O
qpair has been allocated. The frequency of the hang
diminishes if a delay is added after allocating the I/O
qpair - until it disappears completely with a 100us delay.
So add a quirk to insert this delay.
Note - the 100us delay was tested by running
the hello_world example app 50000 times.
