scsi: hisi_sas: Start delivery hisi_sas_task_exec() directly

[ Upstream commit 0e462085 ]

Currently we start delivery of commands to the DQ after returning from
hisi_sas_task_exec() with success.

Let's just start delivery directly in that function without having to check
if some local variable is set.
