969dde0d10 Fix crash when adjusting volume via button while audio device is disabled
When both input and output are disabled, UpdateDeviceState() sets dev_ to
nullptr. Pressing a volume button calls SetOutputVolume() which previously
called esp_codec_dev_set_out_vol(dev_, volume) without null-checking dev_,
causing a crash via ESP_ERROR_CHECK.

Fix: Add null guard for dev_ and mutex lock for thread safety. The volume
is still saved via AudioCodec::SetOutputVolume() and will be applied when
the device is reopened by UpdateDeviceState().
