usb: gadget: audio: Fix a missing error return value in audio_bind()
commit 19b94c1f9c9a16d41a8de3ccbdb8536cf1aecdbf upstream.
If 'usb_otg_descriptor_alloc()' fails, we must return an error code, not 0.
Fixes: 56023ce0fd70 ("usb: gadget: audio: allocate and init otg descriptor by otg capabilities")
