hostapd: fix phy parameter in iface_update_supplicant_macaddr

The function was using phydev.name (e.g., "phy0.0") instead of
phydev.phy (e.g., "phy0") when calling wpa_supplicant.phy_set_macaddr_list.
This is inconsistent with all other wpa_supplicant ubus calls in the same
file which correctly use phydev.phy.
