Enable USB audio offloading which allows to play audio via a USB-C
headset with lower power consumption and enabling some other features.
This can be used like the following:
$ amixer -c0 cset name='USB_RX Audio Mixer MultiMedia1' On

always set when this function is called hence the passing of the val

commit 257d2d7e9e798305d65825cb82b0a7d1c0511e89 upstream.
In the later patch, we're going to issue the PCM sync_stop calls at
disconnection. But currently the USB-audio driver can't handle it
because it has a check of shutdown flag for stopping the URBs. This
is
the state change more strictly. The unexpected state
change is now handled as an error.
