target: pass the se_task to the CDB emulation callback
We want to be able to handle all CDBs through it and remove hacks like always using the first task in a CDB in target_report_luns. Also rename the callback to ->execute_task to better describe its use. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
