scsi: hisi_sas: Wait until error handling is complete

SATA devices are lost when FLR is performed while the controller and disks
are in suspended state.

This is because the libata layer is called to initialize the SATA device
during controller resume. If FLR is executed at this time, the IDENTIFY
command fails. As a result, the revalidate fails, and the SATA device is
disabled by the libata layer.

Wait until error handling completes.
