Runyu Xiao 6c97817e20 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.
