ALSA: snd-usb: operate on given mixer interface only

commit 1faa5d07a93fc5b0a4a5254fc940a79e20b55540 upstream.

When creating the mixers for an USB audio device, the current code looks
at the host interface stored in mixer->chip->ctrl_if. Change this and
rather keep a local pointer to the interface that was given when
snd_usb_create_mixer() was called.
