Fix HDR tone mapping stuck on SM device

Browse source 
Tone-mapping an HDR video with MediaCodec on sm-s908u1 was timing out.
The reason for that is that the decoder was dropping frames, and the
ExternalTextureManager was therefore never propagating the end-of-stream
signal.

There was already a workaround for a similar issue but restricted to
sm-f936b. Removed the model check as the bug is probably present on more
devices.
