scsi: hisi_sas: Set .phy_attached before notifing phyup event HISI_PHYE_PHY_UP_PM

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8IL6H


CVE: NA

----------------------------------------------------------------------

Currently in directly attached scenario, the phyup event
HISI_PHYE_PHY_UP_PM is notified before .phy_attached is set - this may
cause the phyup work hisi_sas_bytes_dmaed() execution failed and the
attached device will not be found.

To fix it, set .phy_attached before notifing phyup event.
