scsi: pm8001: Modify task abort handling for SATA task

When we try to abort a SATA task, the CCB of the task which we are trying
to avoid may still complete. In this case, we should not touch the task
associated with that CCB as we can race with libsas freeing the last later
in sas_eh_handle_sas_errors() -> sas_eh_finish_cmd() for when
TASK_IS_ABORTED is returned from sas_scsi_find_task()
