[M120 Migration] Don't invoke Init of DecoderBuffer when size is 0

For EME case, in SubmitEsPacket, if using tz_handle, the
data of DecoderBuffer should be null, or else crash could
happen in esplusplayer_submit_trust_zone_packet, because it will try to
copy this memory if it's non-null..
When convert media::mojom::DecoderBufferPtr to media::DecoderBuffer,
"new media::DecoderBuffer(0)" will make data of DecoderBuffer non-null,
let's check the input size and don't invoke Initialize() of DecoderBuffer
if size is 0.
