usb: gadget: audio: queue wLength-sized requests
On Audio class, the wLength field of the Setup packet, contains the data payload size of the following Data phase. Instead of harcoding values, use wLength. This also fixes a bug where Gadget driver had to receive 3 bytes, but it was queueing a ZLP. Signed-off-by: Felipe Balbi <balbi@ti.com>
