ALSA: ctl: Fix ioctls for X32 ABI [ Upstream commit 6236d8bb2afcfe71b88ecea554e0dc638090a45f ] The X32 ABI takes the same alignment like x86-64, and this may result in the incompatible struct size from ia32. Unfortunately, we hit this in some control ABI: struct snd_ctl_elem_value differs between them due to the position of 64bit variable array. This ends up with the unknown ioctl (ENOTTY) error. The fix is to add the compat entries for the new aligned struct.
