Subject: ALSA: timer: Fix broken compat timer user status ioctl

From: Takashi Iwai <tiwai@suse.de>

commit 3a72494ac2a3bd229db941d51e7efe2f6ccd947b upstream.

The timer user status compat ioctl returned the bogus struct used for
64bit architectures instead of the 32bit one.  This patch addresses
it to return the proper struct.
