Add back ifdef QCOM_COMPRESSED_AUDIO_ENABLED for sound/compress_params.h

Motorola Qcom devices haven't completed a 3.4 kernel and use a 3.0.31
kernel.  This brings back ability to use audio-caf on these devices.
This was originally part of commit b0f0fce093190136a2def290051a2102be2ba0e4
    audio: Initial bring up of QCOM added audio feature(jb_cho).
