[PATCH v3 14/28] sound: usb: pcm: Export fixed rate check USB SND API

[Wesley Cheng]

Some modules will handle calling snd_usb_endpoint_open() instead of the USB
SND framework.  The USB SND endpoint open function added a new argument to
determine if the connect USB device can support multiple sampling rates.
