[Android] Prevent modeswitch when native_window is invalid

[peak3d]

Description

If kodi is in paused state of a video which was started with display mode switch, screen changes (like automatic screen off / changes regarding HDMI port) can lead to segfaults.

Reason is that Android does not provide a native_window but kodi tries to perform a mode switch on it.
