Camera: Fix null pointer access

Browse Source 
If a device is rebooted then the RecentTasks contains task list but
topActivityInfo could be null. In this case, if a camera device is
opened from a process without activity then CameraServiceProxy could
access null topActivityInfo.

Bug: 272428586
Test: Manual test with the OEM attention service
