hal: VTS fix for supported channel mask

- HAL output stream does not override default supported
  channel mask value. VTS client fails as requested
  channel mask(MONO) is not listed in supported channel
  mask

- HAL Output is opened based on config passed and
  local supported configuration. Output supported
  channel mask should be overridden with output stream
  channel mask
