Many system/vendor modules assume that wifi service is up by the time they run. This is no longer the case since wifi stack now starts a little later in the bootup sequence (to support pluggable wifi stack module for mainline). If any of these modules invoke a WifiManager call, a) Return an appropriate dummy value if the API returns a value b) Raise a RemoteException if the API returns nothing (void). Bug: 139492857 Bug: 137650946 Test: Verified that SUW & CNE receiver no longer crashes with the stack traces in the linked bugs. Also, verified that SUW still can connect to wifi networks & detect when wifi auto-connects after SUW comes up. Test: Verified wifi/softap toggle from Settings/Sysui.
