target: remove the task_lba field in struct se_task
Now that we don't split commands the lba field in the task is always equivalent to the one in the CDB, even in cases where we have two tasks due to a BIDI transfer. Just refer the the lba in the command instead of duplicating it in the task. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
