scsi: hisi_sas: Fix some issues related to asd_sas_port->phy_list
Most places that use asd_sas_port->phy_list are protected by spinlock
asd_sas_port->phy_list_lock, however there are still some places which miss
grabbing the lock. Add it in function hisi_sas_refresh_port_id() when
accessing asd_sas_port->phy_list. This carries a risk that list mutates
while at the same time dropping the lock in function
hisi_sas_send_ata_reset_each_phy(). Read asd_sas_port->phy_mask instead of
accessing asd_sas_port->phy_list to avoid this risk.
