SnapdragonCamera: Fix FC caused by mSession Null

There are lots of FC caused by mCameraDevice/mBuilder/mSession Null,
In the condition:
1. Between opening camera app and not ready to preview.
2. App pause, and then resume to app
3. Restart session by makeup or flash mode change
4. restart all by change camera devices
Checking NULL and add illegal state handler is a work around way.
