Fix PepperVideoDecoderHost to avoid crash when swithing to SW decoder.

Fix PepperVideoDecoderHost to avoid crash when swithing to SW decoder.

Previously PepperVideoDecoderHost could crash when falling back to software
decoder. The problem was that it wasn't handling the case when there is
an outstanding texture request for the plugin. Fixed it by dismissing
outstanding texture requests when switching to SW decoder.
