Revert input buffer count for the SoftAAC* decoders back to 4.
This improves the netflix bandwidth change responsiveness.
With the old count of 32 the audio decoder running at a higher
priority would starve the video decoder for about 1 sec while
draining the input data.
I haven't been able to break any stream playback using MediaCodec
using the lower count, even though I'm sure I had a good reason
to increase it in the first place (see bug 6478823)
