scsi: hisi_sas: Fix I/O errors caused by hardware port ID changes

The hw port ID of phy may change when inserting disks in batches, causing
the port ID in hisi_sas_port and itct to be inconsistent with the hardware,
resulting in I/O errors. The solution is to set the device state to gone to
intercept I/O sent to the device, and then execute linkreset to discard and
find the disk to re-update its information.
