scsi: target: Drop sess_cmd_lock from I/O path
Drop the sess_cmd_lock by:
- Removing the sess_cmd_list use from LIO core, because it's been
moved to qla2xxx.
- Removing sess_tearing_down check in the I/O path. Instead of using that
bit and the sess_cmd_lock, we rely on the cmd_count percpu ref. To do
this we switch to percpu_ref_kill_and_confirm/percpu_ref_tryget_live.
