ASoC: codecs: rx-macro: fix accessing compander for aux

Browse Source 
[ Upstream commit 42c709c4e1ce4c136891530646c9abd5dff3524f ]

AUX interpolator does not have compander, so check before accessing
compander data for this.

Without this checkan array of out bounds access will be made in
comp_enabled[] array.
