scsi: hisi_sas: Fix spinup failure for SAS SSP devices in Active_Wait state
SAS HDDs powered up with RNOT=1 wait in Active_Wait state for a
NOTIFY(ENABLE SPINUP) primitive and keep returning NOT_READY with
ASC/ASCQ 0x04/0x11, causing endless mid-layer retries and spinup
failure.
Parse the sense data in the slot completion path and, when
LU_NOT_READY_NOTIFY_REQUIRED is returned by a directly-attached SSP
device, queue work that sends the primitive from process context
(sl_notify_ssp() contains msleep()). The work takes a runtime PM
reference with pm_runtime_get_if_active(), pairing with
pm_runtime_put_sync() in the work, so the controller stays resumed until
the primitive is sent.
