Currently during SSR IPA events such as AP DISCONNECT/ STA DISCONNECT are not sent and also wlan ipa interafces are not deregistered. After SSR when host sends AP CONNECT/ STA CONNECT and register interafce IPACM will reject as for previous events before SSR there are no disconnect events. This leads to data come via exception path instead taking IPA HW route as interface headers are not registered. In this fix send IPA UC disconnect events and deregister interafces during SSR.
