mixer: try to fix a possible bugdevs/bu5hm4n/mixer_bug

for the case the default sink was removed the gadget will get a new
  default sink again, for the case of pa there is the possibility that
  at this time the sink is still the default one, but the sink gets
  removed. so we better set the default index to -1 and return just some
  sink for the case the default is deleted.
