cx231xx_close_extension and hence cx231xx_audio_fini() are called with the cx231xx device lock held, but snd_cx231xx_pcm_close() also grabs that mutex when closing the file on behalf of arecord. There seems to be no reason to wait for sound card resources to be released, so let the release be asynchronous. Tested with a Hauppauge 955Q (2040:b123) and Linux 5.9.6; the hang described in the bug no longer occurs and disconnecting the device correctly terminates arecord with ENODEV.
