scsi: hisi_sas: Directly call register snapshot instead of using workqueue

Currently, register information dump is performed via workqueue, regardless
of the trigger mode (automatic or manual). There is a delay in dumping
register through workqueue, the exact register information at trigger time
cannot be obtained.

Call register snapshot directly instead of through a workqueue.
