ALSA: pcm: oss: Return -ENODEV instead of -EFAULT in snd_pcm_oss_open()
When try_module_get() fails in snd_pcm_oss_open(), the owning module is
going away and the device is no longer usable, so -EFAULT ("bad address")
is the wrong error. Return -ENODEV, matching the other unavailable-device
paths in this function(the NULL pcm check and the card->shutdown check).
This changes the errno reported to userspace on this rare race.
No other behaviour changes.
