octave: libinterp/dldfcn/audiodevinfo.cc annotate

annotate libinterp/dldfcn/audiodevinfo.cc @ 19517:22e2f11424b3

avoid more warnings in audio code * audiodevinfo.cc: Avoid unnecessary use of this-> and eliminate shadowed variable warnings. Use initialization in class constructors. Pass octave_value and matrix objects by const reference instead of by value.
