topology: add more buffering to media pipe after src 

Currently we have 1.5 times buffering after SRC in media pipeline. This
will not work for S24 or S32 playback as SRC will use the bigger buffers
with non-integer sample rate conversions as 44.1kHz to 48kHz. So add as
big buffer after SRC as before it.
