IPACM: clean wlan NAT ifaces during modem SSR

Wlan-driver will disconnect/reconnect to IPA after modem
SSR and bootup again where framework already send
add_downstream to IPA and resulted in offload failed.
The workaround is to self delete NAT ifaces for wlan
related instances during SSR and cache the downstream
event before wlan restarts.
