Revert "ALSA: usb-audio: Split endpoint setups for hw_params and prepare"

This reverts commit ff878b40.

Unfortunately the recent fix seems bringing another regressions with
PulseAudio / pipewire, at least for Steinberg and MOTU devices.

As a temporary solution, do a straight revert.  The issue for Android
will be revisited again later by another different fix (if any).
