wcte12xp: Disable vpmadt032 companding by default.

This fixes a regression in 2.2.0 where certain configurations will fail
patloop test or have repeated HDLC aborts because the VPMADT032 is
modifying
the clear channel or d channel data streams.  This restores the behavior
to
how it was in dahdi-linux 2.1.0.4.
