usb: gadget: f_uac1: fix ep address for get sample rate

Browse Source 
The f_uac1 use ep address 0x81 and 0x01 to get sample rate,
so it can only support uac1 ep1-in and ep1-out to get playback
and capture sample rate, it has limitation for USB composite
device (e.g. RNDIS & UAC1). This patch use in_ep->address and
out_ep->address instead of the fixed addresses.
