Remove unnecessary setInputFormat

setInputFormat calls registerInputStream and will cause VideoFrameProcessor to
reconfigure. We don't need to call it when setting up the VFP
(in `onReadyToInitCodec()`). Rather, we wait until `onOutputFormatChanged()`
called (this output format refers to mediaCodec's outptut format) to register
the input stream.
