[SCSI] mvsas: fixed timeout issue when removing module

Browse Source 
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.
