ALSA: pcm: Fix ioctls for X32 ABI

commit 513ace79b657e2022a592e77f24074e088681ecc upstream.

X32 ABI uses the 64bit timespec in addition to 64bit alignment of
64bit values.  This leads to incompatibilities in some PCM ioctls
involved with snd_pcm_channel_info, snd_pcm_status and
snd_pcm_sync_ptr structs.  Fix the PCM compat ABI for these ioctls
like the previous commit for ctl API.
