From: Xiangliang Yu <yuxia...@marvell.com>

- Root cause is libsas will clear asd_sas_port
  phy_mask value in sas_port_deform after triggering
  destruct workqueue, but the workqueue will send
  sync cmd and still need phy_mask value.
  Now, mvsas using asd_sas_phy setting instead of
  asd_sas_port setting.
