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().
