Subject: [PATCH v31 32/32] ALSA: usb-audio: qcom: Notify USB audio devices on USB offload probing

If the vendor USB offload class driver is not ready/initialized before USB
SND discovers attached devices, utilize snd_usb_rediscover_devices() to
find all currently attached devices, so that the ASoC entities are notified
on available USB audio devices.
