Condat audio_Init(): rm setting of sidetone level
The default sidetone level in the absence of audio mode loading
is just that, a basic default without any promises of good tuning.
In the original TCS211 code this default sidetone level was set in
two places: first in L1 init of ABB-via-DSP registers (set to -17 dB),
and then initialized again in Condat audio_Init(), this time set to
-5 dB. The present change removes the redundant second initialization.
The default sidetone level is now -17 dB instead of -5 dB with this
change, but again it is just the default; all serious users are now
expected to use audio mode config files.
