ALSA: control: Return -ENODEV instead of -EFAULT in snd_ctl_open()
When try_module_get() fails in snd_ctl_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 card check and the snd_card_file_add() failure).
This changes the errno reported to userspace on this rare race.
No other behaviour changes.
