ALSA: pcm: Zero-clear reserved fields of PCM status ioctl in compat mode
In compat mode, we copy each field of snd_pcm_status struct but don't touch the reserved fields, and this leaves uninitialized values there. Meanwhile the native ioctl does zero-clear the whole structure, so we should follow the same rule in compat mode, too.
