ALSA: pcxhr: initialize mutexes before requesting threaded IRQ
pcxhr_probe() requests pcxhr_threaded_irq() before initializing
mgr->lock, even though the threaded handler takes that mutex.
Initialize the manager locks before request_threaded_irq() so an
early interrupt cannot run against uninitialized mutex state during
probe.
