[PATCH 13/13] scsi: qedi: always wake up if cmd_cleanup_req is set

[Mike Christie <michael.christie@xxxxxxxxxx>]

If we got a response then we should always wake up the conn. For both
the cmd_cleanup_req == 0 or cmd_cleanup_req > 0, we shouldn't dig into
iscsi_itt_to_task because we don't know what the upper layers are doing.

We can also remove the qedi_clear_task_idx call here because once we
signal success libiscsi will loop over the affected commands and end
up calling the cleanup_task callout which will release it.
