Subject: [PATCH] rtlwifi: btcoex: add scan_notify within ips_notify if RFON
Git-commit: ee373844849cdc69f18607311c56179f5be1be69
Patch-mainline: v4.16-rc1
References: FATE#326906
Three steps of connection procedure are scan, enter/leave IPS, auth.
There is no scan between leaving IPS and sending auth, but btcoex use scan
as an important clue that indicates user is going to connect. So add scan
notifications in ips_notify to correct btcoex's state.
