Headsets for proper disconnecting need to disconnect profiles in specified
order(by ex. disconnect a2dp, then sink and hfp at the end). Instead of
adding separate callbacks for disconnecting each profile, now adding only
one callback in audio/device.c for calling audio disconnect functions in
correct order. New disconnect callback works similarly to dev_disconnect
from audio/device.c
