scsi: hisi_sas: Add SATA FIS check for v3 hw
Add a check ERR bit of status to decide whether there is something wrong with initial register-D2H FIS. If error exist, PHY link reset the channel to restart OOB. Directly call work HISI_PHYE_LINK_RESET replacing disable_phy_vx_hw() and enable_phy_vx_hw().
