ALSA: usb-audio: Don't call usb_set_interface() at trigger callback
The PCM trigger callback is atomic, hence we must not call a function
like usb_set_interface() there. Calling it from there would lead to a
kernel Oops.
Fix it by moving the usb_set_interface() call to set_sync_endpoint().
Also, apply the snd_usb_set_interface_quirk() for consistency, too.
