hostapd: ucode: handle null config in iface_set_config again

config_reset and shutdown call iface_set_config(name) with no config, but
the null-config guard was dropped in the MLO rework, so config.phy
dereferenced null and threw: config_reset reset nothing and shutdown left
hostapd-created interfaces behind. Restore the guard, removing the stale
config entry and tearing the interface down via iface_config_remove.
