usb audio: check proxy_prepare() errors in opne_input_stream()

Make sure that open_input_stream() reflects audio parameters
modifications done by proxy_prepare() and returns an error with
proposed parameters if needed.
Alos do not overwrite adev->device_sample_rate when opening an
input stream as this is driven by the output stream.

Bug: 37949012
Test: audio capture, playback and calls over USB headset.
