usb: gadget: Fix synchronization issue between f_audio_source
Race is happening when both audio_pcm_close() and audio_send()
executes in parallel.
When the PCM session is closed, the substream attribute of the
audio_dev structure is set to NULL in audio_pcm_close().
As there is no synchronization protection for the audio_dev subtream
attributes in audio_send(), it is causing NULL pointer dereference.
Hence fixing the issue by adding proper synchronization protection
for the audio_dev subtream attributes in audio_send().
